SPECIFICATIONS
Input Voltage:
105-125 VAC, 47 to 420 Hz, single phase.
Output Voltage Setting:
Output is factory preset to
within ±2% (1 to 9 volt models) or ±1% (10 to 75 volt
models) of the nominal output voltage.
T/C terminal (Output Voltage Trim Adjustment):The
T/C terminal can be used to trim the output more
precisely to the nominal voltage rating by connecting an
external resistor from the T/C terminal to either the + or –
terminal.
Polarity:
Output is floating. Either positive or negative
terminal may be grounded.
Ambient Operating Temperature:
–20 to +71°C.
No derating required.
Storage Temperature:
–55 to +85°C.
Temperature Coefficient:
From 9 to 75 volts, typically
0.015%/°C; 1 to 8 volts, 0.03%/°C.
Impedance:
0.07 ohms at 1 kHz and 0.2 ohms at
10 kHz (approx.).
Weight:
7 oz. (Case size ES-10)
13 oz. (Case size EL-10)
1 lb. 3 oz. (Case size EL-13)
1 lb. 15 oz. (Case size EL-20)
Mounting:
May be mounted on printed circuit board or in
socket (see page 34).
OPTIONS
230 Volt Input:
All models can be alternately furnished
for operation on an input of 210 to 250 VAC,
47-420 Hz. To order, add suffix “–230” to model number
and $10.00 to price. Requires two additional days.
Rugged encapsulated construction and generously
derated components assure years of reliable operation.
PC Board mounting mini-modules are also available with
dual outputs - see page 34.

About Acopian’s 3 Day Shipment Guarantee:
In 1964, Acopian initiated its “3 Day Shipping Guarantee.” Since then our product
offerings have expanded to include many more lines of power supplies that ship
within 3 Days as well as others that ship within 6 or 9 Days. These guarantees
apply to every model in the Acopian catalog.
Our unique 3-day shipping guarantee has prompted many questions. Below are
some of those most often asked:
What does Acopian’s 3-day shipping promise mean?
It means that power modules listed in this catalog are shipped within 3 days after
we receive your order. High Voltage, Redundant, Rack Mounting, Systems and
certain Switching power supplies are shipped within 9 days.
Has Acopian ever failed to meet this promise?
Never.
Do options affect shipping time?
The 230 volt input option and moisture/fungus-proofing option require two
additional days. All other options do not affect shipping time.
Is the 3-day promise affected by quantity? Suppose we need 50 or 100 pieces?
The 3-day promise applies to orders for five or less modules. (Two or less for 9-day
items). If requested, Acopian will ship five pieces of a larger order in 3 days and,
with consideration of your requirement, schedule the balance. (Since each
shipment is processed and priced as a separate order, for lowest prices request
shipment in one lot.)
What if I need four or five different models? Does the 3-day promise still apply?
Yes. Guaranteed 3-day shipment applies to one model or to a combination of models.
Do I have to ask for 3-day shipment of my order?
3-day shipment is automatic. In fact, you must tell us if you want the shipment delayed.
How long after you ship will I have the power supplies?
Transportation time varies with the carrier used. Unless otherwise requested,
Acopian ships small orders by UPS Ground.
You say Acopian has never failed to meet the 3-day promise. How do you do it?
Our facilities have been designed and equipped to meet our 3-day shipment
promise. When your order is received, your power supplies are built specifically for
you and shipped within three days. We do not ship from stock. (For this reason, we
are unable to accept returns for credit.)
I’ve seen other power supply manufacturers advertise “same-day shipment.”
Isn’t that better than 3-day shipment?
A typical vendor’s “same-day shipment” advertisement can only be fulfilled if the
power supplies you need are in stock. Otherwise, a four to six week delay is not
unusual before inventory is replenished and your order is shipped.
Acopian’s 3-day shipment promise applies to ALL 3 Day models (larger units ship
within 9 Days) and is not dependent on the quantity in stock. We build each unit
after the order for that unit is received. If an order is needed faster, often times we
can ship in less than 3 days.

…can customize power supplies for you
If a standard power supply does not meet all of your
requirements, speak with one of our engineers. We can
often modify the specifications, ratings and configuration
of a supply. We can also combine several power supplies
into a Multiple Output Power System with the operating
features you specify (such as meters and switches) and
ship it within 9 Days!
…has a 5-year warranty
This is typical: One of our customers sent us an old power
supply with a note indicating that the supply had been in
continuous use since 1972 (33 years!), but he had
recently noticed that the output voltage was low. We
found that the capacitors had dried up, replaced them and
returned the supply to the customer, who thanked us and
said he intends to keep using it. We focus on making
power supplies that will last a long time. There are power
supplies that cost less than ours, or that are smaller than
ours, but you won’t find any that last longer than ours. All
too often, low-priced supplies are densely packed, run
hot, have short lifetimes and short warranties. All Acopian
metal-cased power products have a 5-year warranty, but
you can expect them to last a lot longer.
Purchase Acopian... 3-day shipment, long lasting
power supplies, and unsurpassed customer service.
“In my business, Acopian is
referred to as bulletproof. It
never fails and lasts forever.”
- Steve Andrews, President
Technical Options, Inc.
If you require shipment even earlier than our standard promise, just let us know,
we can usually ship sooner. We welcome the opportunity to work with you.
“If Acopian made automobiles,
I’d buy one without question.”
