DESCRIPTION

Unipower Telecom's LVD400 and LVD600 Series of low-voltage disconnect panels are designed for maximum flexibility. They can be used for either load or battery disconnect. The two mounting position (3.5 inches) high panels can be configured as single or dual (A/B) disconnects. The disconnect contactor is rated at 400 or 600 amperes.

Form C relay contacts indicate an LVD alarm. Disconnect and reconnect voltages are field settable.

The A and B sections of the dual LVD panel can be separately configured for 24 or 48 volts and positive or negative ground. The LVD front panels can be specified for either a 19- or 23-inch relay rack mounting.
