20EB12 Acopian Power Supplies, 20EB12 Datasheet - Page 23

• Manufacturer Part Number: 20EB12
• Description: AC to DC Power Supply, 20V Output
• Manufacturer: Acopian Power Supplies

Series B power supplies are ideal for powering digital
circuitry, test sets, instrument bridges, and process
control transmitters. Many models have regulation of
±0.1% or better. All components are generously derated
STANDARD FEATURES
SPECIFICATIONS
Input Voltage: 105-125 VAC, 50-400 Hz, single phase.
Output Specifications: See pages 22 and 23. Series B
supplies have model numbers beginning with the letter B.
Remote Voltage Adjustment/Sensing: Available as an
option. See below.
Polarity: Output is floating; either positive or negative
terminal may be grounded or floated up to 300 volts
above ground.
Temperature Coefficient: 0.02%/°C (Typical).
Ambient Operating Temperature: 0 to +71°C.
Storage Temperature: –55 to +85°C.
OPTIONS
Overvoltage Protection: An internal preset overvoltage
protector is available. To order, add prefix “V” to the model
number, and add $25.00 to the standard price of models
with outputs of 1.5 to 70 volts; $35.00, for 75 to 200 volt
outputs.
Remote Voltage Sensing: Provision for sensing the
output voltage across the load, so that drops in the load
lines are compensated, is available on all models. (This
option also permits the use of an externally located
potentiometer to adjust output voltage.) To order, add
prefix “R” to the model number. No increase in price.
Terminal Strip Cover: Clips on. To order, add suffix “M”
to model number and $5.00 to price.
230 Volt Input: All models can be alternately furnished
for operation on inputs of 210-250 VAC, 50-400 Hz.
To order, add suffix “–230” to model number and $25.00
to price. The “–230” option requires two additional days.
• Short circuit proof (electronic current limiting)
• May be mounted on any of three surfaces
• Completely serviceable

SERIES B: GENERAL PURPOSE POWER SUPPLIES
to insure a long and trouble-free life, and they use the
same rugged construction as the Series A line.
Overvoltage protection and other options are available.
Mounting: Threaded mounting holes permit mounting to
a chassis, cabinet wall or bracket. To mount from the
power supply side of the mounting surface or for DIN rail
mounting, see accessory Mounting Kits on page 37.
