Programmable semi conductor monitoring relay 12V 100/150A

The programmable monitoring relay is a voltage monitoring module, regarding voltage and time delay parameters. It enables the user to set voltages for turning on and off loads according to the manufacturers´ sepcifications. 
The time delay function allows for a certain hyteresis. This prevents quick switching at quickly alternating voltages.
Not only disconnecting and connecting devices or batteries is possible, also a warning voltage can be set. When this voltage is exceeded or fallen below a warning lamp lights up.  
Another big advantage of the programmability is that the semi conductor relais can be used as closer and as opener. 

The semi conductor relay is a newly developed relay without wear. It automatically disconnects 12V devices if the battery falls below a certain point (which can be set) and so prevents the battery being overly discharged. Developed with an external alarm connector it can already send an alarm signal (8-audio&/Video) prior to setting a disconnecting voltage.
The configurable semi conductor relay with low voltage protection allows the user to connect a second battery via a Override-switch.
Made with anodised aluminum and coated connectors as well as steel safety nuts it prevents problems often occuring with other relays like corroded contacts since it does not rely on moving parts to open or close the conduction. Also it does not have a seperating diode, which is why it does not heat up even when under high load.

Prevents overly discharging the battery. The battery is switched off after it falls below a set voltage.
Alarm connector for long distance monitoring and identifiying low voltage.
Weather resistant, compact size and small height.
Very low voltage drop.
100% semi conductor design 
No moving parts which cause light arcs or electrical hissing.
Automatic switching off, protection from overheating, overload, overcurrent and mass loss.
Configurable as opener or closer
Bridgeable through remote controll port
Free configuration of all switching voltages
Configurable time delay (switch hysteresis)
not dependent on polarity


The programmable monitoring relay can be used for many things:
  • combination of battery banks and/or load dissapation
  • battery low voltage protection (closer)
  • battery over load protection (opener)
  • parallel operation in emergencies
  • fully automatic turning on and off of loads with a set voltage
  • safe for low voltage operation
  • fully automatic turning on and off of batteries with a set voltage
  • safe and reliable long distance monitoring of heavy loads up to 150A

  • IP65 certified 
  • protection from overheating with automatic disconnection.
  • seperate connection for emergency operation. 

Technical data:
