AC Mains Controller now available!
The main function of the mains controller is to provide easy powering on and off of mains power
without the need of a heavy duty mains switch, but allows you to use a low power low voltage rated switch
of which there are many available or it can be enabled via the common 12v trigger voltage found on many commercial pre amps.
For safety and isolation the 12 volt trigger is opto-isolated.
One of the more nicer features is the addition of a DC offset detection circuit which can monitor six amplifier outputs concurrently. These monitored inputs can also be used for thermal, over current, over voltage protection.
In the event of an amplifier fault the detection circuit will latch and power down the amplifiers power supply instantaneously, removing the need for loudspeaker protection for each amplifier channel and immediately protecting the power amplifier from further damage.
The HPA-Power one main board is self powered via a high quality encapsulated 4VA mains transformer and has power on and protection status LEDs which can be extended off board to the power amplifier front panel.

The PCB size is 95mm x 90 x 20mm. Price is $139.00AUD.

30 amp contact rated output relay.
Switch up to 4KVA Power Transformers.
Opto-Isolated 12v Trigger for power on, low power manual switch optional.
Built-in 6 channel amplifier DC offset fault detection.
If DC offset fault is detected in any one of the monitored channels, power is turned off instantly.
Can also be used to monitor for over-temperature using a normally open thermal switch.
Other fault detection using external sensing are possible, such as Over-Voltage, Over-Current, etc.
