Power supplies

Power supplies for HVAC controllers and HVAC sensors. 24 VDC, 12 VAC or 24 VAC are commonly used supply voltages in the HVAC industry. Switching power supplies have a high efficiency and can handle a wide input voltage range. They generate a stable 24 VDC supply voltage. Their overload protection increases the safety of your electrical installation. The safety transformers are basic linear power supplies for 12 VAC or 24 VAC.
