275A Cont Motorized Dual Operation VSS (Voltage Sensitive Switch) - Deutsch Connector

These Voltage Sensitive Switches (VSS) automatically sense connected battery bank voltages and provide optimal, efficient charging of the second bank. The VSS allows for independent battery banks to be combined or isolated based on the presence of a charging source (such as an engine alternator or battery charger), while also offering remotely activated, high current, emergency parallel connection. 

Features:

  • Deutsch Connector
  • Dual battery sensing
  • Manual override option
  • Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless steel nuts, and high temperature, fiber reinforced plastics

Features (Engine Run Sensing):

VSS will engage when the voltage on either start or house battery reaches 13.7 volts. If the combined battery voltage drops below 13.0 volts 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 volts. If the combined battery voltage drops below 12.2 volts 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 volts. If voltage drops below 13 volts and stays above 12.2 volts on either start or house battery while engine is running, the VSS will stay engaged. 

Features (Remote Emergency Parallel Function):

  • The 701-MDVS-D 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 will stay engaged. If not, it will disengage
  • The advantages of using a high current VSS is that it will cover your dual battery charging requirements and emergency parallel operation in one unit

Very useful if you don't want to explode!
Style: 90 Lumens
Found the unit a bit difficult to adjust on the hard hat but got it dial in eventually. Also impacted by the need to mount goggles on the helmet, that might be rare, but this was my situation working around chemicals. nice and bright. batteries last a couple of days with intermittent use approx. 3.5hrs a day. A bit of a pain to unscrew the cover on batteries but that's the nature of the beast to make sure no sparks escape. Would highly recommend the product. Most other comparable products are around double the price. BTW, the packaging looked like the driver dropped it on the road and ran over it a couple times...but it still worked. UPDATE #1: After a few months of usage, the height adjustment is starting to fail. As I walk, the light begins to droop until it's shining down in front of me. Dissappointed that the adjustment didn't last longer. I might be able to discover a way to lock it back in, but have not taken the time to examine the mechanism yet. UPDATE #2 9-2018: The adjustment problem has now reach its ultimate end. The hinge on bottom has basically disintegrated. Now, when I put batteries in and tighten the screw, the bottom hinge pops loose. The product is no longer usable. The hinge is just cheap plastic, that is a shame, I kind of expected better from nightstick. However, it still seems to be the best option vs. price available so I am planning to order it again. Hope I can get 3 years of intermittent use out of the next one. I do really like it when it is working...lite and bright.

Fantastic. They vary in thickness to accommodate different size punctures, they look nice, good value for the money, the sand out the tire and internal belt to stop leakage. and they easy enough the use.
