5. HARDWARE DESCRIPTION

5.2.3 POWER SUPPLY

The DBF power supply can be 48-125 VDC or 110-250 VDC rated. The operating margin of the power supply is + 20%, and is galvanically isolated from the rest of the relay's circuits. The power supply provides ± 12 VDC to the analog circuitry and the output relays, and ± 5 VDC for the digital circuits.

5.2.4 KEYBOARD AND DISPLAY

The DBF display at the front of the relay is liquid crystal type and consists of two rows of 16 characters each. The display has background light with variable lightness adjustable by a potentiometer located on the rear of the front cover plate.
