Solar controller for PV applications DELTATHERM® PHM

The DeltaTherm® PHM is the ideal solution for using excess PV current for the control of different loads. Heat pumps, electric immersion heaters, and charging stations for electric vehicles can be controlled as needed. All the while household power has absolute priority. Each load can also be supplied with mains current on a time-controlled basis. Furthermore, the DeltaTherm® PHM measures the electric loads at the energy meter which can be visualised via VBus.net. Increase in self-consumption Reduction of heating costs Control of a heat pump Control of a wallbox Control of up to 3 electric immersion heaters (via auxiliary relays) Household current priority Can be used with all PV systems Time-controlled backup heating (with mains current) DeltaTherm® E sensor Inputs: 3 current inputs and 3 voltage inputs for SW16 current sensors Power supply: 100 – 240 V~ (50 – 60 Hz) Supply connection: Y Standby: 1.22 W Rated impulse voltage: 1,0 kV Data interface: VBus® Functions: energy measuring unit Housing: plastic, PC (UL 94 V-0) Mounting: DIN rail in the domestic distribution board Indication/Display: 2 operating control LEDs Ingress protection: IP 20 / DIN EN 60529 Protection class: II Ambient temperature: 0 … 40 °C Pollution degree: 2 Dimensions: 71 x 90 x 58 mm DeltaTherm® PHM Inputs: 5 Pt1000 temperature sensors (2 of them convertible to switch) Outputs: 3 electromechanical relays, 2 potential-free extra-low voltage relays and 1 PWM output (convertible to 0-10 V) Relay outputs: 1 (1) A 240 V~ (electromechanical relay) 1 (1) A 30 V⎓ (potential-free relay) Total switching capacity: 3 A 240 V~ Power supply: 100 – 240 V~ (50 – 60 Hz) Supply connection: X Standby: < 1W
