The CTRS4CBSP-DUAL is an obstruction lighting control box designed for controlling and monitoring RedDot LED low intensity and medium intensity aviation obstruction lights. Incorporated a power converter, CTRS4CBSP-DUAL allows users to input two types of voltage and converts to lower voltage for electrical safety works. The user-friendly interface is intuitive for users to monitor operation status and easily configure functions.

There are four light outputs (max. 1A load/output). Practically, for example, for input voltage 220VAC & 48VDC, each output connects one OM2K or F864 medium intensity light, or up to eight OL32/OL100 low intensity lights.

With a Form C dry alarm relay (NO&NC), the control box is capable of transmitting the obstruction lighting system’s failure to users’ alarm devices, when light failure, power-off or photocell failure.

A PHC01 photocell is used for automatically switching on and off the obstruction lighting system from dusk to dawn. Bypass switch on the 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 converters from overload. A surge protector enhances protection against voltage fluctuation and lightning strikes.
