ECS

Economy Power Supply

August 1994

Reliability - Simplicity - Isolation
The ECS Economy Power Supply is the low-cost
solution for many of the difficulties that can be encountered when powering 24V process instrumentation. It
is an ideal process loop component for use with noiseprone 2-wire transmitters and data communications
equipment, in most cases exceeding performance
specifications of higher-priced supplies.
Protect Your Investment—ECS outputs incorporate full-time short-circuit and overload protection.
Liberal use of heat sinking materials and case venting
mean burn-out is not a problem.
Protect Loop Accuracy—Unit power-to-output
isolation is 2500Vrms, standard. Ground loops
between power source and transmitter are eliminated.
Safeguard Sensitive Signals—Superior line and
load regulating capabilities protect surge-sensitive
transmitters and data modules from line irregularities.
Noise and resultant data loss due to line power
fluctuation is effectively under control.

Compact thermoplastic housing snaps quickly and
securely onto standard G-type and Top Hat rails.

Features
Two Drives From Which to Choose
The ECS is available in both 70 and 200mA models
covering a wide range process instruments’ power
requirements and loop loads.

• Superior Isolation. 2500Vrms protection means
process signals will not be affected by even severe
ground loops, motor noise, or other electrical
transients.
• Switchable Line Powering. The standard ECS,
while configured at the factory according to customers’ specified 117Vac or 230Vac, can be fieldreconfigured.

NON-ISOLATED
2-WIRE
XMITTER

RECEIVING

• Simple Adjustability. Calibrate the ECS to meet
your requirements. The front panel potentiometer
provides ±10% voltage output variance.

Full Line of Power Supplies
Moore Industries offers a comprehensive line of power
supplies including: the DIN-mounted DPS family; the
PPS, PPX, and SPS available with angle bracketing
and explosion-proof enclosures; and the SMP surface
mount unit, designed to work with rack-mounted
instrumentation.
