by Shane Henson — June 25, 2012—Controlled Power Company, a U.S. manufacturer of a full line of commercial, industrial, and medical electrical power solutions, recently announced the availability of its SwitchLITE Model EZT (Emergency Zone Transfer Cabinet) Automatic Transfer Switch for emergency lighting applications.
SwitchLITE Model EZT allows dimmable lighting fixtures to function as essential emergency lighting, and may be used in such facilities as theaters, auditoriums, restaurants, casinos and worship centers.
The SwitchLITE Model EZT is a UL 1008-listed product, designed to automatically transfer four, six, or eight individual 20-amp branch circuits to emergency power when normal power fails, and then back to normal power once it has been restored. Upon transfer to emergency power, lighting fixtures that are dimmed (or off) are brought to full illumination to provide safe egress, says Controlled Power Company.
The SwitchLITE Model EZT also satisfies the requirements of the National Fire Protection Association standard NFPA 70 as related to Automatic Transfer Systems, and is compliant with the ANSI / NFPA 110 Standard for Emergency and Standby Power Systems. Ideal for use in a dimmer rack application, together with an emergency lighting inverter (or standby generator) as the emergency power source, the SwitchLITE Model EZT’s rugged and intelligent design brings performance and reliability to critical emergency lighting systems, says the company.
Other specific features include:
- Soft Start Control with user-selectable zero to two-second voltage ramp to accommodate the high inrush current associated with energizing certain types of lighting fixtures.
- User-Adjustable Transfer Delay to and from emergency power to best fit specific applications.
- Remote Command Transfer allows external contact(s) to initiate the automatic transfer of all circuits from normal to emergency power during critical NFPA-mandated test periods.
- The RCT input may connect to a Controlled Power Company emergency lighting inverter’s “test active” contact to initiate the transfer of emergency circuits.
- As the Controlled Power lighting inverter automatically performs and logs NFPA-mandated tests, all emergency lighting loads are energized to validate system testing.
- A local keyed test switch is provided to simulate a power failure during manual testing of the emergency lighting and life safety system.
- User-Adjustable Transfer Delay to and from emergency power to best fit specific applications.
