Publication time : 2018-6-25 10:33:58 
Cintrong DVR dynamic voltage restorer (IP33 outdoor type) is applied to Tanzania Telecom base station.

1.Input voltage range: 400V + 30%, (TN-S system)

Frequency: 40Hz-70Hz

Capacity: 40kVA, 50kVA, 80kVA, 120kVA

2. Output

Voltage: 400V (5% adjustable)

Frequency: 50Hz

Voltage stability: < ±1%

Frequency stabilization: < ± 0.01%

Efficiency: >90%

Three-phase voltage balance mode: automatic balance

Voltage stability time: < 2mS

3. Protection

Overvoltage protection: input line voltage exceeds 400V+30%, automatic shutdown, reduced to 400V-20% automatic boot.

Under voltage protection: input line voltage is lower than 400V-30% automatic shutdown, up to 400V+20% automatic start.

Lack of phase protection: automatic shutdown

Overload protection: overload 2S automatic shutdown

Bypass: manual bypass function, emergency power supply when equipment fails.

4. Instructions
