Operation:
Input Voltage Protection:
User-settable undervoltage and overvoltage thresholds. Alarm output and LED indicators for voltage conditions.
Overcurrent Protection:
Shuts down if excessive current flows through for too long. Restarts after 1 minute.
Temperature Protection:
Monitors temperature to prevent overheating and damage. Automatically restarts after cool down.

Protects against ground loss issues. Restarts after resolving the ground loss problem.
Programming:
Refer to the programming table in the manual. Briefly make connections to set programming positions indicated by LED feedback.
FAQ
Q: What should I do if the PB-MBW shuts down due to undervoltage?
A: Check the battery voltage and charging system. Ensure proper connections and thresholds are set. Restart the PB-MBW after resolving the undervoltage issue.
PB-MBW 40/60
Battery Guard MOSFET 40A / 60A
Description
The Battery Guard MOSFET PB-MBW40/60 (hereafter referred to as the PB-MBW) is an intelligent, user-programmable, fully waterproof battery guard.
The PB-MBW has expansion options for an off switch and an alarm output to which a buzzer, LED strip or relay can be connected. To minimise EN losses, the PB-MBW is equipped with two bolt-on connections: input+ and output+. The remaining connections (neg, remote input, programmable input and alarm output) are connected via separate 6.3 mm faston connectors. The PB-MBW is equipped with a bright status LED which displays how it is functioning. The PB-MBW also features an “automatic board system detection”, which enables it to automatically detect whether it is connected to a 12 V or a 24 V system.
Installation
Install the PB-MBW on a cooling metal surface to allow it to dissipate the
heat it generates. Use a power supply cable of up to 50 cm for the PB-MBW.
This is the only way to accurately monitor the battery voltage.
Please note!
- The product may only be installed by qualified electricians who are fully aware of the requirements for working with high battery voltages.
- The use of faulty connection material and/or excessively high gauge wiring may damage the PB-MBW.
- A short circuit between the battery’s positive and negative terminals can cause serious damage to the system.
- Always use the correct fuses.
- Use a 1.5 mm2 cable directly from the battery to the PB-MBW for the negative (–) connection. Do not use this connection for anything else.

Operation
Input voltage protection
The input voltage protection values (undervoltage threshold, undervoltage
reset, overvoltage threshold and overvoltage reset) can be set by the user.
See “Programming” for an explanation of how to set these values.
Undervoltage
When the PB-MBW’s input voltage drops below the undervoltage threshold for 15
seconds, the alarm output will turn on. The LED will also indicate
undervoltage. The PB-MBW will shut down one minute later and the alarm output
and LED will turn off.
When the PB-MBW’s input voltage exceeds the reset threshold for 5 seconds, the
PB-MBW will turn back on, and the LED will indicate that the PB-MBW is active
again.
Overvoltage
The PB-MBW will shut down if the input voltage exceeds the overvoltage
threshold for 0.5 seconds. The alarm output will indicate (at a frequency of 1
Hz) that overvoltage has been detected. The LED will also display this
information.
Overcurrent protection
The current through the PB-MBW is measured constantly. If an excessive current
flows through the PB-MBW for too long, the PB-MBW will shut down to prevent
damage to both the PB-MBW and the connected equipment. The PB-MBW will turn on
again after 1 minute.
Temperature protection
The PB-MBW will shut down immediately if its temperature exceeds 85 °C. The
LED will indicate a fault. The PB-MBW will turn on again after 1 minute if the
temperature has dropped below 75 °C.
Ground Loss protection
The PB-MBW will shut down
if it detects that the negative (–) is disconnected on the power supply side.
The LED will indicate a fault. The PB-MBW will turn on again after 1 minute.
Remote
A switch can be installed between the remote input and the negative (–) to
manually disable the PB-MBW output. The PB-MBW will shut down immediately when
the connection is made. The PB-MBW will turn on again when the connection is
broken.
LED
The LED has two functions. The first is to indicate the PB-MBW’s status. The
different options are outlined below. The second is to programme the PB- MBW.
This operation is described in the section “Programming”.
LED CODE
- Two short blinks (± 0.15 sec.), then off for a long time (± 3.5 sec.).
- One blink (± 0.5 sec.), then off (± 1.5 sec.).
- One blink (± 1.0 sec.), then off (± 1.0 sec.).
- Three short blinks (± 0.25 sec.), then off for a long time (± 2.5 sec.).
- LED is off.
FAULT DESCRIPTION
- PB-MBW is enabled.
- PB-MBW is disabled because the remote has been activated.
- Undervoltage or overvoltage detected.
- PB-MBW has been shut down for one minute due to one of the following causes:
- Ground loss, temperature protection, current protection, low output voltage.
- PB-MBW has been shut down due to undervoltage.
Programming
- To enter programming mode, a connection must be made between the programme input and the negative (–). The LED will blink once if the connection has been maintained for ± 2 seconds. Once this is done, the connection must be broken.
- The same connection must be made briefly again to set the correct position number—the LED will light up as feedback.
- At that point, programme position #1 is selected. The user can briefly make the connection again to select programme position #2, etc., etc..
- If no connection is made for ± 4 seconds, the LED will display the set state again. (Example:
- programme position #4 is set by a user, the LED will blink 4 times)
- Two types of settings are available. Positions 1 through 10 set the undervoltage threshold and reset values. Positions 11 and 12 set the overvoltage threshold and reset values. These settings must be selected individually.
- The programmed positions are retained when the battery voltage is disconnected.
