For REAR MOUNTING of TG5,6,9 &13, TH11, and G5D cases, remove original
screws(4) and use 8-32 Type F self-tapping screws. They should extend
at least 5/16” (0.312”) into the power supply case.
(When rear mounting G5D case, a hole is required in the mounting
surface for access to the Section 2 output adjustment.)
For REAR MOUNTING of TN6T and TN8H cases, remove original 6-32 screws(4).
These screws may then be used for mounting, provided they
extend at least 1/4” (0.250”) into the power supply case.

Acopian general purpose duals furnish two completely
independent outputs, either identical or different, in less
space and at less cost than two equivalent single output
supplies. Thousands of output voltage/current rating
combinations are available. Mounting and system wiring
are simplified. Quality components, generously derated,
insure long-term reliability.
HOW TO ORDER: Select two sections (from the same table)
on pages 30 and 31. The complete model number is the
combination of the two sections selected. Example: The
combination of section 5GT20D and section 8GT50D is Model
5GT20D-8GT50D. Always assign the lower voltage section
first. (Two of the same section can also be selected.) For
pricing purposes, add the costs of the individual sections selected.
SPECIFICATIONS
Input Voltage: 105-125 VAC, 50-400 Hz, single phase.
Output Specifications: See pages 30 and 31.
Short Circuit Protection: Delivers current surges without
damage—built-in fuse protects supply against prolonged
overloads and shorts.
Polarity: Outputs are floating. Each output may be
independently connected to provide any combination of
positive and negative voltages. Outputs may be floated up to
300 volts above ground.
Temperature Coefficient: 0.02%/°C (Typical).
Ambient Operating Temperature: –10 to +71°C.
No derating required.
Storage Temperature: – 55 to +85°C.
Case size: G5D.
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.
OPTIONS
Overvoltage Protection: Two separate, preset overvoltage
protection circuits, one for each output. To order, add prefix “V”
to model number and add $30.00 to the standard price for 1.5
to 70 volt outputs; add $50.00 if either or both outputs are
greater than 70 volts.
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 the standard price.
The “–230” option requires two additional days.
