BATTERY MANAGEMENT
150A BATTERY MONITOR + TAIL LIFT CONTROL
This Unit was designed for use with Tail Lifts Controllers. The Unit monitors
the Battery Voltage.
Once the Battery Voltage has dropped below the predetermined minimum
level (see table ) for more than 30 seconds the Lamp flashes and the Piezo
sounds.
If the Battery Voltage is not raised to an acceptable level (see table) within 2
minutes, the Solenoid operates to disconnect the supply for 4 minutes.
During this period the Lamp and Piezo remain on continuously.
This 2 minutes, four minutes cycle is repeated until the Battery Voltage is raised to an acceptable level (see
table).
A “Start” connection is provided, which reconnects the supply and resets the Timers. This can be
activated by one of four methods - wiring diagrams are supplied with the Unit.

E860 24V BATTERY MONITOR WITH 135A ELECTRONIC OVERLOAD TRIP
This unit was designed to monitor the voltage of a battery and switch power
to an external circuit. An electronic overload trip is included this disconnects
the power if the current taken by the external circuit exceeds 135A.
During normal operation the Amber lamp indicates that the supply is
connected to the external circuit.
Battery Voltage Control:
Once the battery voltage has dropped below 23.5V for more than 30 seconds the
Red lamp flashes and the Piezo sounds. If the battery voltage is not raised to 26V
within 2 minutes the E860 disconnects the supply for 4 minutes during this period
the Amber lamp is off, the Red lamp and piezo remain on continuously.
This 2 minutes, four minutes cycle is repeated until the battery voltage is raised to 26V.
An optional “Start” connection is provided, which reconnects
the supply and resets the timers this can be activated by one
of the following:
1. The “W” terminal on the alternator. This connection
ensures the alternator is charging the battery before the
warnings are stopped and the supply is reconnected

Electronic Overload Control:
If at any time the average current drawn by the external circuit exceeds 135A then the power will be disconnected
and the Amber lamp is switched off. Pressing the reset button resets the Overload circuit, on releasing the button
power is reconnected and the Amber lamp switches on.
Note: pressing and holding the reset button disconnects the supply for as long as the button is pressed
Battery Voltage and Overload Control:
Pressing the reset button whilst the battery is disconnected by the battery monitor has no effect.
If after an overload and whilst the external circuit is disconnected the battery becomes low, then the battery monitor
circuit takes control and after the 4 minute timed period resets the overload circuit. Power will then be automatically
reconnected to the external circuit. The battery monitor will continue with the 2 minutes warning etc.

E821 200A SOLID STATE SWITCH
The Solid State Switch uses MOSFET technology to provide an economical and reliable method of
switching high power DC loads.
The Solid State Switch has slow turn-on and turn-off times to reduce inductive voltage spikes.
Unlike relays and solenoids, the control voltage and switching voltage use the same negative ground
Precautions
1. Inductive loads must be diode suppressed.
2. Tighten the Solid State Switch power terminal nuts properly. If the nuts are not tight, the Solid State
Switch will be damaged by heat generated when the power is ON.

E942 30V 60A SURGE PROTECTOR
This unit was designed to protect delicate electronic equipment connected to a generator / battery system
from voltage spikes. The unit is fitted between the generator and the battery.
In normal use the unit acts like a very low value resistor with a typical voltage drop of 0.21V at 60A and will
not affect the charging of the battery.
If there is a fault in the generator and the generator’s output voltage rises above 30V the unit will limit the
output voltage to 30V.

E1032 12V BATTERY MANAGEMENT UNIT
This unit was designed to monitor the voltage of a battery and connect or
disconnect a load of up to 200A.
When the battery voltage is above the Switch “On” voltage (13V) the load is
connected to the battery.
When the battery voltage drops below the Switch “Off” voltage (12.5V) after
a short delay the load is disconnected. The Unit then switches to low power
mode until the battery is recharged and the voltage rises above the Switch
“On” voltage, then the load is reconnected to the battery.
An override pin allows the load to be connected* for emergency use only.
To reduce power consumption to a minimum (10mA “On”, < 1mA “Off”) a
latching contactor is used.
When the contactor is “On” the coil is pulsed to ensure it remains on
When the contactor is “Off” the coil is pulsed for approx. 2 minute before
the unit goes to low power mode.
The Switch “On” and Switch “Off” voltages are factory set but can be
adjusted by the customer.
An internal light emitting diode (led) is used as a multipurpose indicator:
1. Led on - the units output is pulsing the contactors coil “On”
2. Led off - the unit is in low power mode
3. Led flashes each time the contactor coil is pulsed
4. Aids setting of the switch “On” and “Off” voltages

load. When power is applied to the override pin there may be a delay of up to 30 seconds before the contactor
switches.
2. Before connecting to the power terminals check the contactor contacts are open. If they are closed apply
power to the “Battery –ve” and “Battery +ve” terminals, the contactor contacts should open.

E1046 12V BATTERY MANAGEMENT UNIT
WITH WARNING
This unit was designed to monitor the voltage of a battery and connect or disconnect a load of up to 200A.
When the battery voltage is above the Switch “On” voltage (13V) the load is
connected to the battery.
When the battery voltage drops below the Switch “Off” voltage (12.5V) the
“Low Battery” warning light emitting diode (led) lights for 2 minutes then after
a short delay the load is disconnected the unit then switches to low power
mode until the battery is recharged and the voltage rises above the Switch
“On” voltage then the load is reconnected to the battery.
An override pin allows the load to be connected1 for emergency use only.
To reduce power consumption to a minimum (10mA “On”, < 1mA “Off”) a
latching contactor is used.
When the contactor is “On” the coil is pulsed to ensure it remains on
When the contactor is “Off” the coil is pulsed for approx. 2 minute before the
unit goes to low power mode.
The Switch “On” and Switch “Off” voltages are factory set but can be
adjusted by the customer.
There are 2 light emitting diode (led) indicators:
Red “ON” is used as a multipurpose indicator:
1. Led on – load is connected (there could be a delay after the led lights
before the load is connected)
2. Led off - the unit is in low power mode
3. Led flashes each time the contactor coil is pulsed
4. Aids setting of the switch “On” and “Off” voltages
White “LOW BATTERY” lights for 2 minutes before the battery is disconnected

E1041 12V 200A SPLIT CHARGE CONTROLLER
This unit was designed to control the charging of a secondary (leisure) battery from the primary charging system.
The voltage of the primary battery is monitored.
During charging when its voltage rises above the Switch “On” voltage (13V)
then the secondary battery is connected in parallel thus charging both
batteries.
After charging when the primary battery voltage drops below the Switch “Off”
voltage (12.5V) and after a short delay then the secondary battery is
disconnected, leaving enough charge in the primary battery to start the engine.
The unit switches to low power mode until the primary battery is recharged and
the voltage again rises above the Switch “On” voltage then the secondary
battery is connected in parallel again charging both batteries.
An override pin allows both batteries to be connected* for emergency use only.
To reduce power consumption to a minimum (10mA “On”, < 1mA “Off”) a
latching contactor is used.
When the contactor is “On” the coil is pulsed to ensure it remains on
When the contactor is “Off” the coil is pulsed for approx. 2 minute before the
unit goes to low power mode.
The Switch “On” and Switch “Off” voltages are factory set but can be adjusted
by the customer.
An internal light emitting diode (led) is used as a multipurpose indicator:
1. led on - the units output is pulsing the contactors coil “On”
2. led off - the unit is in low power mode
3. led flashes each time the contactor coil is pulsed
4. aids setting of the switch “On” and “Off” voltages
