The CBL08A is an obstruction lighting Control box designed for controlling and monitoring Lansing LED low intensity and medium intensity aviation obstruction lights. Incorporated an AC/DC power converter, CBL08A allows users to input AC voltage (85-265VAC) and converts to 48VDC/24VDC/12VDC for electrical safety works. The user-friendly interface is intuitive for users to monitor operation status and easily configure functions and for monitor lighting operation system for the following failures: burned out lamp, photocell, power failure. & flashing rate control There are eight light outputs (max. 1A load/output). Practically, for example, for input voltage 48VDC, each output connects one ZG2K or F864 medium intensity light, or up to Seven DL32/DL100 low intensity lights. With a Form C dry alarm relay (NO&NC), the control box is capable of transmitting the obstruction lighting systems failure to users alarm devices, when light failure, power-off or photocell failure. A PT01 photocell is used for automatically switching on and off the obstruction lighting system from dusk to dawn. Bypass switch on interface panel allows users to bypass the photocell for permanently lightening or testing. DIN-rail terminal blocks save wiring time and enhance wiring safety. A 2P circuit breaker is effective in protecting the control box from overload. A surge protector (reach 20KV) enhances protection against voltage fluctuation and lightning strikes.
