Product Introduction
Built with finned heating tubular resistors and a dual-channel power source, this load bank delivers 21kW of capacity across three load steps (each 1+2+4kW at 230Vac).
It ensures accuracy with ±5% voltage tolerance (short-term operation) and ±3% load element tolerance, while features like thermal emergency cut-out, air circuit breaker protection, and forced-air cooling (706 CFM via four 150mm fans) guarantee safe, stable operation even in demanding environments (up to +50°C ambient temperature).
