摘要: A recirculating bath includes a main power input configured to receive an alternating current and heating element that is selectively coupled the input. The in response activation signal having duty cycle. cycle of determined based on voltage current, with being reduced increase current. thereby de-rated at higher voltages. unit provides direct independent portions bath, such as motors compressor pump. operate range
