Dowei Electric DC Power Supply GZDW

Product catalog summary

General Description:

The DC Power Supply adheres to standards such as IEC 61204, ANSI/IEEE Std C37, and NEMA, and is certified by ISO 9001, KEMA, CESI, CE, TUV, UL, and ASTA.
It features seismic design compliance with ETGI-1.020, IEEE Std 693, and NCh2369, and structural design compliance with ASTM A325, ANSI/AISC 360, and AWS D1.1.
Designed for high altitudes up to 5000m, it serves as a DC auxiliary power supply for switchgear, breakers, and control and protection systems.
Communication protocols supported include RUT/CDT/MODBUS, with interfaces such as RS232/RS485 or TCP/IP.

Typical Specification:

AC Input: Voltage range of 380V±20% and frequency range of 50Hz±10% or 60Hz±10%.
DC Output: Rated voltage of 220/110V, with a voltage regulation range of 180-286V and rated current of 5-200A. Output current limiting range is 5%-110%, with regulating voltage and current accuracy both ≤0.5%.
Ripple coefficient is ≤0.1%, and conversion efficiency at full load output is ≥94%.
Dynamic response features a recovery time of ≤ 200 μS and overshoot of ≤ ± 2%.

Ambient Condition:

Insulation strength is 2KVac for 1 minute, noise level is ≤55dB at 1m distance.
Operational temperature range is -5℃ to +45℃, with transportation and storage temperature range of -40℃ to 70℃.
Humidity tolerance is 0-90% with no condensation.

General Rating:

Protection functions include output overvoltage, current limiting, short circuit, over temperature, module parallel, and over current protection.

Battery Compatibility:

Compatible with Lead–acid (VRLA) and Ni-Cd batteries, with capacities ranging from 7AH to 3000AH.

Typical Dimensions:

Available in dimensions of 2260×800×600mm and 2260×800×800mm.
