Emergency Return Systems

UV2 Single Phase Series

UV2 Single Phase Series
(Multiple Voltage Models Available)

Compact, wall mounted steel cabinet contains the electronic circuitry and batteries.

Automatic activation turns unit on during power failure to power entire controller, thereby keeping all safety circuits intact.

480VAC model provides regulated output to primary side of main step down transformer for shorter installation time. Can be used in most applications where the incoming main line power is 480VAC, three phase.

All safeties stay in place while powering the complete controller.

Automatic reset when normal power returns.

A set of dry contacts is provided with each unit to signal the controller that it is under emergency power, aid in power transfer and pilot other relays.

Diagnostic bank of light emitting diodes (LEDs) permits troubleshooting at a glance, saving time.

Low battery cutoff circuitry prevents battery and unit damage caused by excessive battery drainage.

On/off switch on the circuit board and interconnection to main line disconnect allow safe maintenance work and expedite periodic system checks.

Lockable battery disconnect switch (optional) allows batteries to be isolated from system when main power is turned off.

Voltage output is regulated to maintain controller stability.

Single, hinged circuit board design allows for simple board or battery exchange.

Separate fusing for batteries, outputs, logic circuitry and battery charger offer extra protection.

VRLA batteries included with unit provide maintenance-free power, eliminating possible build-up of dangerous fumes.

Optional reverse phase relay can be added if required by elevator specifications.

Dimensions: 12.5"H x 12.5"W x 8.5"D.
