What this product is
Architecturally, the DZY4850H-TTI employs a dual-stage switch-mode topology: an input Active PFC boost stage that accommodates an ultra-wide utility range of 90V AC to 290V AC while suppressing total harmonic distortion (THD), followed by a high-frequency isolated full-bridge LLC/ZVS DC-DC converter yielding an ultra-clean -48V bus. Control is governed by a high-performance onboard DSP managing hardware protections, blind-mate backplane pins, and robust EMI suppression filters compliant with CISPR 22 / EN 55022 Class B standards.
What problem it solves
Designed for remote wireless base stations plagued by unstable rural grids, severe voltage surges, and broad diurnal temperature swings, the DZY4850H-TTI prevents recurring rectifier failures caused by undervoltage burnouts, thermal tripping, and overvoltage back-feed. Operating stably between -25°C and +70°C with redundant hardware OVP circuitry, it safeguards sensitive transmission transceivers from damage and reduces field maintenance MTTR to minutes without downtime.
Who and where it is for
Ideal for 4G/5G macro and micro base station outdoor enclosures, central office telecom power plants, railway trackside signaling power cubicles, enterprise private network hubs, and high-reliability edge computing micro data center DC racks.
