TOA Electronics VX-2000DS UL2572/864-Listed Emergency Power Supply for VM-3000
The VX-2000DS Emergency Power Supply UnIt’supplies DC backup power to each component in the VM-3000 system. It keeps the 2 x 12 V sealed lead batteries charged, compensating for the temperature of the battery charging voltage. When AC Power is disrupted, the VX-2000DS is automatically switched to the backup batteries.
