What this product is
Architecturally, the R4815N1 employs a two-stage power conversion circuit: an active power factor correction (APFC) boost pre-regulator delivering >0.99 power factor and low THD across variable line conditions, followed by an isolated high-frequency DC/DC resonant converter with synchronous rectification. Fully compliant with international safety and electromagnetic standards such as IEC/EN 60950, CISPR Class B, and ETSI 300 019, it utilizes blind-mate backplane connectors supporting live live-insertion without arcing.
What problem it solves
The R4815N1 prevents common field failures caused by unstable power grids, severe brownouts, transient overvoltage surges, and localized thermal choking. Its ultra-wide operational window of 85V AC to 300V AC prevents dropped telecom connections in rural networks prone to severe line drops. Integrated thermal derating, continuous short-circuit protection, and autonomous overvoltage latching ensure hardware survival, eliminating unnecessary emergency maintenance truck rolls.
Who and where it is for
Ideal for 4G/5G remote radio units (RRU) and baseband unit (BBU) cabinets, FTTx central office OLT installations, microwave transmission repeaters, industrial automation RTU enclosures, and distributed -48V DC telecom power frames.
