Power Supply
The integrated DC power supply of the BT100 is a separate circuit board mounted to the underside of the electronics chassis and is capable of 60 VAC or 90 VAC powering. The waveshape of the input voltage can be either squarewave or sinewave. The power supply incorporates
2.5A at 24 VDC. The AC input to the power supply is between 38 VAC and 90VACrms, in two ranges, with a line frequency from 50 Hz through 60 Hz. A precision output regulator protects against overcurrent and short circuits. If a short circuit is detected, the power supply shuts down and the regulator initiates a sequence of line test pulses at approximately
The power supply contains a two position 60/90 V selector that sets the
38 VAC or 55 VAC. The BT100 is shipped with the selector in the 60 V position which is the standard configuration. The selector should be switched to the 90 V position only for a 90 VAC system. This sets the
