DMS-EB-AC/DC
100-264Vac Power Supply
Accessory Board for
DMS-30PC/LCD Panel Meters
Features
? Allows meters to operate from 100
to 240Vac (50/60Hz)
? Screw-type terminal block connections
? Provides 1500V isolation between AC
supply and input signal
? Has prototyping features of the standard
DMS-EB board
? On-board solder gaps for decimal
point placement
? Same size as DMS-30/40 meters
2.02" (51.3mm)L x 0.82" (20.8mm)W
? Low cost
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 connec-
tions and eliminates the need for any extra wiring harness connectors.
The DMS-EB-AC/DC board includes provisions for installing several user-
supplied 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 compat-
ible 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.
