Introduction

2.0 Introduction
The HPC is a professional power control product designed primarily for use in
performance spaces, but has many additional applications. Each of the 12 channels
incorporates a full power dimmer circuit and two high current relays connected as
shown in Figure 1.
Input
Figure 1: Channel Organisation
The "Isolate" relay ensures the output can be fully switched off with a real "air gap"
between the input and output, while the "Bypass" relay completely bypasses the
dimmer circuitry ensuring a clean undistorted mains output. Hence each channel can
be used to safely switch power to non-dimmable loads such as moving lights, LED
fixtures, video screens and walls, gobo rotators, fog machines, and other accessories,
or alternatively smoothly dim conventional incandescent loads. Channels may be
individually set to On, Remote Switch, Remote Dim, or Off.
The HPC is controlled using DMX-512-A via a standard 5-pin socket on the front panel.
RDM functionality is provided to enable remote configuration and status readback via
a suitable RDM controller. The dimmed outlets and power entry are located on the
rear panel. The HPC provides easy to use in-built test functions and facilities.
