Review on πŸ”‹ LM YN LM YN Battery Emergency Switch Control Module DC12V Max 150W Power Failure Auto-Switch Backup Battery - Ideal for Network Equipment, Electrical Appliances, and More. by Alexis Hughes

Revainrating 4 out of 5

A good product. I will buy again.

A few days later - Good quality PCB, no mounting holes. Easy connection. No real complaints. Works as stated. It would be nice if the output could be programmed to "OFF" when the system was powered up. until the main power is switched off. As"duty". This means that the emergency lighting remains switched off until the power fails. I need to add a photocell (+$8) between the emergency light and this switch to achieve this. A star is deducted for the lack of mounting options or holes, and there is no "off" option for standby mode.

Pros
  • Electronics
Cons
  • Piggy Bank Price
