Power Module - Type 12HF

The G.R.A.S. Power Module Type 12HF is a power supply for single-channel, low-noise measurements using the matched, low-noise preamplifiers and high-sensitive microphones of a G.R.A.S. low-noise measuring system.





The Type 12HF provides:

• polarisation voltage (200 V) for the condenser microphone
  
• voltage supplies (±15 V) for powering the microphone preamplifier
  
• a response setting of pressure or free field
  

When fitted with the above matched preamplifiers and microphones, the Type 12HF supports the specifications of a G.R.A.S. low-noise measuring system.
