VSR - Dual battery charging voltage sensitive relays

REMOTE OPERATED DUAL BATTERY CHARGING VOLTAGE SENSITIVE RELAYS(VSR) WITH EMERGENCY PARALLEL

The VSR switch utilizes the same operation as the MD battery switches and is packed with features which complimet the MD range.

 

FEATURES
• Dual battery sensing
• Remote emergency parallel function 701-MDVS and 720-MDVS can be operated through a momentary button on the dash which will parallel the batteries for a present time of 10 minutes. Once this 10 minutes has passed, if the voltage is up high enough for the voltage sensitive switch to operate, it twill stay engaged. If not, it will discharge.
• Engine run sensing VSR will engage when the voltage on either start or house battery reaches 13,7 Volt. If the combined battery voltage drops below 13,0 Volt and the engine is not running, after 5 seconds the contacts will open and stay open until the start or house battery voltage exceeds 13,7 Volt. If the combined battery voltage drops below 12,2 Volt and the engine is running, after 5 minutes the contacts will open and stay open until the start or house battery voltage exceeds 13,7 Volt. If voltage drops below 13,0 Volt and stays above 12,2 Volt on either start or house battery while engine is running, the VSS will stay engaged.
• Manual override option
• The VSR will cover your dual battery charging requirements and emergency parallel operation in one unit
