CHINT · Intelligent capacitor controller
Product overview
The CHINT ZT-830 monitors electrical parameters and controls compatible intelligent capacitors for low-voltage reactive-power compensation. The illustrated ZT-830GB is the simultaneous three-phase compensation controller; ZT-830FB is the separate hybrid simultaneous / split-phase version.
Technical selection summary
| Illustrated model | CHINT ZT-830GB simultaneous-compensation controller |
|---|---|
| Control function | Automatic detection and switching control of compatible intelligent capacitors according to grid reactive-power conditions |
| GB network capacity | Up to 30 simultaneous-compensation intelligent capacitor units |
| FB network capacity | Hybrid version: up to 20 simultaneous-compensation units plus 10 split-phase units; use the FB wiring diagram |
| GB power-supply reference | AC 380 V ±20%, 50 Hz ±5% in the retained Global reference; match the actual GB terminal diagram |
| GB power consumption | Less than 5 W in the retained Global reference |
| Communication / protocol | RS485 intelligent-capacitor communication; the Global reference describes standard Modbus for host-computer communication |
| Compatible capacitor reference | BAGB for the matching simultaneous-compensation network; FB selection and wiring must match the specified BAGB / BAFB arrangement |
| Display / operation | LED digital display, parameter viewing/setting, manual/automatic operation and simulation switching test |
| Protection functions | Overvoltage, undervoltage, undercurrent, overtemperature and harmonic-related protection; disconnects capacitors and blocks output when limits are exceeded |
| Stored settings | Configured parameters are retained after power loss according to the catalogue |
| Panel cut-out | 113 × 113 mm; verify enclosure depth against the exact version drawing |
| Standards reference | JB/T 9663-2013 and DL/T 597-1996 |
The unit is a controller, not a capacitor bank. Networked capacitor-unit counts are not the same as hardwired output stages. Match GB or FB, sampling/wiring and the communication interface before ordering. D-suffix DC 12 V output controllers are different versions and must not inherit the GB/FB RS485 host-communication claims. Use the exact catalogue edition and compatible capacitor network.
Typical applications
- Intelligent low-voltage power-factor compensation cabinets
- Monitoring and coordinated switching of compatible smart capacitor units
