The RLH DC/DC Converter card provides an isolated 24VDC or 48VDC output designed to power up to 12 Fiber Optic Link cards. Engineered for industrial telecom applications, these converters provide an isolated and regulated DC output from station batteries or other widely fluctuating DC sources. The RLH DC/DC Converter cards are designed to fit into any RLH Fiber Optic Link card housing or shelf, and can be combined with additional converters for a high density DC power solution.
