INSTRUCTION SHEET
Switching Power Supply
PS3X Series
Confirm that the delivered product is what you have ordered. Read this instruction sheet to make sure of
correct operation. Make sure that the instruction sheet is kept by the end user.
SAFETY NOTE
In this operation instruction sheet, safety precautions are categorized in order of importance to Warning and
Caution :
The PS3X switching power supplies are designed for installation in a Industrial control panel. This product
cannot be used outside of equipment. Embed this product inside an appropriate enclosure before using the product.
Warning no ices are used to emphasize that improper operation may cause severe personal injury or death.
Do not use the switching power supply on control equipment in medical equipment, aircraft, aerospace craft, trains, and
atomic equipment where malfunction of the switching power supply may cause severe personal injury or threaten human
life. These switching power supplies are designed for use on general electronic equipment such as communication
equipment, instrumentation equipment, and industrial control equipment.
Make sure that the operating conditions sa isfy the values described in the catalog. Confirm the specification values
before designing the equipment to use the switching power supply and before supplying power. Contact IDEC if you
have any question.
Do not modify or repair the switching power supply. Modifica ion or repairing of the switching power supply by users may
cause electrical shocks, damage, fire, malfunction, and other heavy accidents.
Do not install the switching power supply where a human body may come into contact while power is supplied to the
switching power supply. Do not touch the switching power supply during operation or immediately after turning off
because some parts are heated and at a high voltage, causing burns or electrical shocks.
Do not connect the output terminals or output lead wires together. Fire or damage may result.
Include a protection in the equipment using the switching power supply in considera ion of malfunction or damage of the
load in case the switching power supply should fail. If the switching power supply should fail, a very high voltage drop
may occur at the output terminals.
Turn power off before wiring the switching power supply. Make sure of correct wiring. Incorrect wiring may cause
electrical shocks or damage.
Caution notices are used where inattention might cause personal injury or damage to equipment.
Make sure of the correct input voltage. Incorrect input voltage may cause blown fuses, fuming, or fire. Make sure of
correct polarity of input and output terminals before supplying power to the switching power supply.
Mounting the switching power supply, make sure that the body has been securely fixed.
Do not touch any part inside the switching power supply. Prevent foreign objects from entering into the housing of the
switching power supply. If the internal parts are touched by hand or foreign objects such as a paper clip or screw
entering into the housing, accidents or damage may occur.
Observe the temperature derating. The operating temperature is the temperature around he switching power supply.
Use he switching power supply within the temperature derating curve. Otherwise, the internal temperature will rise and
damage may be caused.
For DC input, make sure to install an external fuse.
Do not turn the output voltage adjustment beyond the limits. Otherwise, the switching power supply may be deteriorated
and damage may be caused.
When damage or malfunction should occur during operation, immediately turn power off and stop the switching power
supply. Contact IDEC.
Do not use or store the switching power supply in environments subjected to a large amount of vibrations or shocks.
Otherwise, damage may be caused.
Do not install the switching power supply in environments exposed to direct sunlight, iron particles, oil splashes,
chemicals, and hydrogen sulfide. Do not use the switching power supply in humid places such as basements or
greenhouses or in low-temperature places such as in freezers or in front of cooler outlet.

Power Supply Installation
For mounting direction of Power supply, refer to the [Fig.2].
For mounting holes dimension of Power supply, refer to the [Fig.4].
Use M3 screw for mounting of Power supply.
The screw leng h should be L (Thickness of Mounting board + d) mm .
(See the right figure )
The mounting screw tightening torque 0.49N m.
Make sure of sufficient convection in consideration of heat radiation.
Do not block the opening of the switching power supply.
Keep at least 20mm clearance around the switching
power supply, except for the opening.
When the derating is in question, provide forced air-cooling.
Connect ground terminal to a proper ground completely.
Use minimum 60 C wire, copper wire only.
The terminal tightening torque 0.8 N m.
< Adjusting the Output Voltage > The output voltage can be adjusted within
VADJ (output voltage adjustment). Turning clockwise increases the output voltage, and turning counterclockwise
decreases the output voltage. Note that the overvoltage protection may work when the output voltage is raised.
< Overcurrent Protec ion > When an overcurrent flows due to an overload, the output voltage drops. When the load is
reduced to a normal level, the normal output voltage is restored. Note that an overload or short-circuit condition
continuing for an extended period of time will deteriorate or damage internal elements.
< Overvoltage Protection >(PS3X-B , -C )The Power supply uses a voltage limit and auto-recovery.
(PS3X-D , -Q , -E )The Power supply uses a manual reset method after power shutdown or hiccup mode. To
recover from output voltage drop due to an overvoltage, turn off the AC input, and turn on he AC input after
approximately 1 minute.
< Insulation Resistance and Dielectric Strength Tests > When making these tests, connect the AC input terminals
together and the output + and - terminals together. Rapid application and interruption of the test voltage will generate a
surge voltage, which may damage the switching power supply.
