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 mechanical connections and eliminates the need for any extra wiring harness connectors.
