Universal DC charge controller



For storage heating systems and electric underfloor storage heaters with DC charge control.

Backlit multi-function display, 4-key operation, error detection, individual heating circuits can be shut off; switching capacity max. 3 A/230 V~, reference variable 0.91 to 1.43 V or -3.6 to -2.85 V DC, adjustable heating curve (extendable temperature setting range 30 °C to 90 °C for residual heat and outside temperature-dependent loading of the storage heating systems), individual raising/lowering of day and night charging, sensor type switchable between standard NTC temperature sensor; (2.43 kOhm/20 °C) and NTC sensor type 30 (500 ohm/20 °C), top hat rail mounting with 3 modular spaces, degree of protection IP20 if installed accordingly. (Note: NTC temperature sensors are not included in the scope of supply), for 0.91 to 1.43 V and -3.6 to -2.85 V DC.

  • Control voltage: 0.91 bis 1.43 V
  • Control voltage 2: -3.6 bis -2.85 V
