AC Load Banks .
DRLB AC Load Banks / RLC Intelligent Load Banks
AC load banks for testing and maintenance of power sources: resistive DRLB 3 kW – 5 MW with 0.1–15,000 A, single- or three-phase, and intelligent RLC 3 kVA – 5 MVA for 110–690 V AC with resistive, resistive-inductive, resistive-capacitive or RLC loads. Load is applied in steps from the local panel or remotely — via RS232/RS485 from a PC or from a PLC remote control box. Meters display current, voltage, frequency, power and temperature. Fan or water cooling, protection class IP20–IP67.
Applications
- Generator set load testing
- UPS and inverter power supply testing
- Data centre and server room load testing
- EV charging station testing
- Testing of circuit breakers and contactors
- Burn-in and simulated load tests
