ER-PSD relay protection test power supply screen

◆ Product Overview
The ER-PSD relay protection test power supply panel is a product designed and manufactured by our company in accordance with the relevant regulations of the Ministry of Energy's "Power Plant and Substation Engineering and Relay Protection Test Instrument Configuration Quota", "Relay Protection Inspection Regulations", and the Ministry of Power Industry's "Key Points for Anti accident Measures of Power System Relay Protection and Safety Automatic Devices". It provides a stable and convenient AC/DC test power supply for on-site relay protection tests and other testing work, and provides reliable guarantees for improving the quality of various testing work, ensuring personal and equipment safety.

◆ Technical parameters
1. Working power supply: three-phase four wire 380V, 50Hz, with two inputs as backup for each other. The two power supplies can be automatically or manually switched on, and can be selected for use with a switch;
2. Rated output:
Communication section:
Rated output voltage: 380V/220V 50Hz three-phase four wire, three-way output;
100V/58V 50Hz three-phase four wire, three output channels;
When the three-phase input is balanced, the output imbalance is less than 1%;
Third harmonic component<3%;
The AC transformer has a capacity of 15KVA and operates intermittently at an hourly load rate of 50%, with a maximum output current of 3 × 22A;
The screen is equipped with 6 single-phase sockets and 1 three-phase socket.

DC section:
DC voltage continuously adjustable from 0 to 250V, with three outputs;
