Telecom DC Power Distribution Frame

DPH01 DC power distribution frame is specialized AC and DC combined power distribution frame for telecom equipments, mainly DC power distribution, and has warning display function as well. It is usually arranged in the head of transmission equipment line in telecom room. Main Features: Voltage and current values are displayed by way of pointer or digital meter or liquid screen display which can indicate power working status quickly and accuratel Having function of checking over voltage, under voltage and air circuit breaker status. Adopting centralized display and audible and visual alarm, with RS485 interface to facilitate failure spot positioning and realize remote control. Can receive outer equipments alarming signal AC power distribution is mainly for illuminating and testing.Can provide lightning protection function(optional) Function and Application Input rating voltage: DC-48V, AC 220V, 50Hz Input Current: no more than 1250A Allowable voltage drop: ≤0.3 (20°C) Insulation resistance: DC≥30MΩ AC≥100 MΩ Insulation Strength: DC :1KV(50Hz AC)/ 1min; Without breakdown or flashover AC :2KV(50Hz AC)/ 1min; Without breakdown or flashover Working Temperature: -5°C 40°C Storage Temperature: -10°C 50°C Relative Humidity : ≤85%(at 25°C±5°C) Can be applied to -48V DC power distribution for equipments in large data machine room, exchange machine room, transmission machine room, etc.
