Power Module - Type 12AG

The Power Module Type 12AG is an 8-channel mains/line operated power supply, but can also be powered by an external DC supply. It is built for multi-channel acoustic measurements, using preamplifiers and condenser microphones.

The Type 12AG has 7-pin LEMO 1B input connectors for microphone preamplifiers. All channels have dual overload indicators, one instantaneous and one latched.

The gain in each channel can be selected individually in steps of 10 dB from 0 dB up to +50 dB. The high-pass filters are 3-pole butterworth filters with a –1 dB cut-off frequency at 20 Hz to remove unwanted low-frequency signals, for example caused by wind-induced noise on microphones.

The cabinet width is half the width of a standard 19” rack. With the rack mounting system Type AK0040, two of these Power Modules can be mounted in a standard 19” rack.

19" Rack-mounting System AK0040
The AK0040 is a shelf for mounting instrument cabinets, e.g. G.R.A.S. Power Modules, and can itself be mounted in a standard 19" instrumentation rack via its flanges. It can house instruments 133 mm high and is wide enough to contain instruments amounting up to a total width of 430 mm.
