PRODUCT OVERVIEW
This low-cost accessory board provides an easy way of powering all DMS-30PC-X-RL (red low-power
models only), as well as all DMS-30LCD and DMS-40LCD (non-backlit, +5V-powered models only) panel
meters from 100-264Vac (50/60Hz). The on-board AC/DC converter provides an isolated +5Vdc to power
the meter’s electronics, while providing 1500Vac isolation between the AC supply and the input signal
being measured. Line power and input signals connect to two rugged, screw-style terminal blocks (TB1 &
TB2) permanently mounted on the DMS-EB-AC/DC. This type of terminal block provides reliable mechani-
cal connections and eliminates the need for any extra wiring harness connectors.
The DMS-EB-AC/DC board includes provisions for installing several usersupplied components that
are required when the meter must be scaled to display non-standard input ranges. The DMS-EB-AC/DC
has provisions for such common applications as attenuation of high input voltages, gain (span) and offset
(zero) adjustments, and direct decimal point placement. The DMS-EB-AC/DC is compatible with all four
input versions of the DMS-30 Series meters (±200mV, ±2V, ±20V and ±200V). Solder gaps, conveniently
placed on the board, are easily bridged or cut to configure the board to meet each application’s specific
requirements.
