Page 11: Section 2 Installation And Operating Instructions
SECTION 2 INSTALLATION AND OPERATING INSTRUCTIONS Programming Connection Connect the remote program signal line to the input connector (J1) as shown below. Check that signal polarity is correct (+ to J1 pin 7, – to J1 pin 6). Wiring for the program line should be either a twisted pair, or a shielded pair, with the shield tied to the power supply chassis. -
Page 12: Operation
M51 Isolated Analog Option DCS Series Operation After appropriate programming mode has been selected, and the external programming voltage source has been connected, the output of the power supply may be varied by adjusting the programming voltage. CAUTION! Never allow the power supply output voltage or current to exceed the rated maximum. -
Page 13: Section 3 Theory Of Operation
SECTION 3 THEORY OF OPERATION General The M51 interface board consists of two functional blocks, the isolation amplifier with input buffer amplifier and associated switching circuitry, and the isolated power supply, which provides power to the input side of the isolation amplifier. Isolation Amplifier The isolation amplifier U1, has a capacitively isolated input stage, which prevents any D.C. - Page 14 M51 Isolated Analog Option DCS Series 14 to approximately 2.5V, the same level as the internal reference in the PWM. The on time of Q1 is controlled to maintain this sensed voltage at 2.5V, which also keeps the main secondaries at pin 6, 7 and 8 regulated.
