PCMT MK II – MODEL FP 4409A
The transformer is designed as a high voltage isolation barrier for data transmission systems passing through hazardous voltage areas.
The product is similar to the PCM Isolation Transformer PCMT (designed for 64K / 2Mbit/s data systems) in that it provides high voltage isolation to 20kV rms but with considerable improvement to the low frequency response. This model is now also applicable to MODEM transmission systems where lower frequency loss figures are of concern.
The transformer is of potted construction and although the overall dimensions are larger to accommodate the changes in internal components, the fixing positions have been maintained to the centres of the PCMT transformer.
