HFP Three Phase Series

HFP Three Phase Series

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

Automatic activation during power failure or brownout to lower hydraulic elevators and to enable doors to be opened at designated landing, eliminating any entrapment of passengers.

HFP 220VAC or 480VAC models will provide 208VAC, 220VAC, 460VAC or 480VAC output for controllers, door motors and retiring cams (not pump motors) of any hydraulic elevator system.

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.
