DF3500-220 switching power supply technical indicators: Reference standard General technical conditions for relay protection system power supply DL/T527-2002 Serial number Technical parameters Remarks 1 Power input: AC/DC-220V (single-phase 220V system) AC/DC-110V (single-phase 110V system) ① The protection device uses single-phase power supply, AC and DC dual-purpose, input power supply error ±30%, divided into 220V and 110V power supply according to the system. Generally, in the urban network system, the protection device is powered by a DC panel, and the power supply requirements are lower; in the rural network system or factory and mine system, the protection device is powered by AC power, and the power supply requirements are high. A Nominal value Single phase (+KM, -KM) or (A or B or C and N) B Error range 220V±30% 110V±30% C Power frequency 50Hz±10% Special requirements for rural power grid system: 220V power input must withstand phase voltage input 300VAC and can work within 4 hours, 450V AC power supply can not work but cannot be damaged, 700V AC 1 minute power supply without spark explosion (can be damaged), and has input overvoltage protection, the protection point is AC380V-AC450V. 2 Power output: V1: 5V/1.5A, V2: 15V/0.15A, V3: -15V/0.15A, V4: 24V1/0.4A, V5: 24V2/0.2A. (V1~V3 common ground, V4 independent ground, V5 independent ground)
