Four 12 V outputs switch together as one bank. Two independently controlled PWM outlets provide dew control and can instead be configured as constant 12 V outputs. The manual specifies 4 A per PWM channel and a 10 A total device limit. Two supplied pigtails convert the 2.1 mm outputs to RCA for heater bands.
The powered hub provides two USB3 and two USB2 ports, with a USB3 Type-B computer connection. Built-in temperature and humidity sensing supports automatic heater adjustment and software environmental reporting.
Stored settings allow standalone use; Unity, ASCOM and INDI provide computer control. The manual specifies −20 to +60 °C operation. The package includes DC leads, two RCA adapters and a 1.8 m USB3 cable.
