• Manufacturer Part Number: B25G210
• Description: AC/DC POWER SUPPLY SNGL
• Manufacturer: Acopian Power Supplies

single output
Mini Encapsulated
SWITCHING REGULATED
DC output (accepts either AC or DC input)
These versatile power supplies mount in a surface
area of only 3.5˝ x 2.5˝, and are available in a choice of
mounting styles. They have a high efficiency and may be
operated through a wide temperature range.
STANDARD FEATURES
SPECIFICATIONS
Input Voltage: 85-130 VAC, 47-420 Hz, single phase, or
120-180 Vdc. DC input may be connected without regard
to polarity.
Output Voltage Setting: Output is factory preset to
within ±2% (5 to 9 volt models) or ±1% (10 to 48 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.
Regulation:
Ambient Operating Temperature: –10 to +71°C.
No derating required through +50°C.
Storage Temperature: –40 to +85°C.
Temperature Coefficient: ±0.02%/°C (Typical).
Humidity: Maximum of 90% relative, non-condensing.
Overload/Short Circuit Protection: Power foldback with
automatic recovery.
Isolation:
• Shipped Within 6 Days
• One Year Warranty
Load: ±0.05% (5 and 6 volt “WL” models, ±0.1%)
Line: ±0.05%
• Compact, lightweight, fully encapsulated
• Short circuit and overload protected
• No heat sinking or forced air required
• Input/output isolation
• Extensive EMI filtering and shielding
Input to output: 1400 Vdc
Input to ground: 1400 Vdc
Output to ground: 400 Vdc

- with screw terminals
or
A common-mode input filter reduces conducted noise,
and the shielded case minimizes radiated energy.
Their outputs may be used in either polarity, and may be
precisely trimmed.
Efficiency: 76% (Typical).
Switching Frequency: 225 kHz (Typical).
Transient Response: Returns to within ±1% of output
setting within 300 µS. Maximum of ±3% output excursion
following a load step change from 50% to 100% of rating.
Holdup Time: 33 mS (Typical, at nominal input voltage
with full load).
Mounting: Models for PC Board mounting may also be
mounted in the socket shown below. For models with
screw terminals, when wall-mounting or DIN rail
mounting is desired, use accessory Mounting Kits on
page 19.
