Telecom DC Power System
A modular DC supply for communication exchanges, mobile base stations, railway repeater equipment and station telecom loads. Select the rectifiers, battery and output arrangement around the communication equipment—not the switchgear operating circuit.
Power for Telecom Loads
The telecom system supplies DC communication loads and manages the associated battery. Although it shares the GZG10 family designation, its output options and rectifier selection differ from the GZG10 DC operating-power system.
- Communication exchanges and transmission repeater stations.
- Mobile base stations and radio communication equipment.
- Railway and power-station telecom circuits.
Input, Output & Rectifier Selection
| Selection item | Listed options / limit |
|---|---|
| AC supply | 380 or 220 VAC; confirm the permitted input variation for the selected version. |
| DC output | 48 or 24 VDC options; confirm polarity and earthing with the load connection. |
| Rectifier module current | 10 / 20 / 25 / 30 / 50 A |
| Module quantity | Up to 24; selected for the load and battery charging duty. |
| Battery capacity | Up to 2,000 Ah; the arrangement depends on voltage and required autonomy. |
| Operating conditions | −10 to 40°C; relative humidity ≤90%. |
The 48 V application is described as −48 V telecom supply. Confirm the required polarity rather than treating every listed DC output as interchangeable. Module and battery limits do not define a universally available cabinet configuration.
Battery Management & Monitoring
Charging and maintenance
DSP-controlled rectifiers support hot-swap replacement. Battery management includes low-voltage protection, temperature compensation, current limiting, capacity calculation and online battery testing.
Status and connection
Monitoring records up to 100 alarms and 10 sets of battery-test data. Listed connection options include RS232, modem and dry contacts. Confirm the monitoring hardware and integration method for the project.
Selection Questions
Is this the same system as GZG10 operating power?
No. This page covers telecom loads. Select telecom output voltage, polarity and rectifier modules independently of the switchgear operating-power system.
Can module count define the maximum supply current?
Do not multiply a module rating by the maximum quantity to specify a complete system. Load current, charging duty, redundancy and distribution must be reviewed together.
Discuss Your Configuration
Share the information you have. A complete specification is not required for an initial enquiry.
- Telecom load voltage and polarity.
- Continuous load current and battery autonomy.
- Available AC supply, installation space and monitoring connection.
Ask for the available catalogue, drawings and technical documents for your equipment.
