General Description
The PJB series of Open Frame Power Supply comes with universal AC input at 85Vac to 264Vac. Other features include low leakage /
Inrush current and conformal coating on the PCBAs to provide protection against dust and chemical pollutants. The built-in active PFC
provides PF > 0.97 and fulfills Harmonic Current Emission according to IEC/EN 61000-3-2. The feature built-in Power Boost of 200% for
10 seconds enables reserve power to be always available for reliable startup of loads with high inrush current, thus eliminating the need
of a more expensive power supply unit at higher power rating. Metal chassis and case cover are available as options for different
installation preferences.
The PJB series is certified for EMI standards according to EN 55032 and EMS according to EN 55024. The products conform to major
international safety standards according to EN/UL 62368-1 standards and are fully compliant with RoHS Directive for environmental
protection.

For safety reasons, please ensure the mounted device is kept at ≥ 4mm (0.16 inch) safety distance at all sides from other components
and equipments. Please insert an insulation sheet between the system and product, if the safety distance is less than 4mm (0.16
inch).
•Use flexible cable (stranded or solid) of AWG No. 22-18. Please refer to Table 1 for the recommended Housing and Terminal.
•For the Remote ON/OFF function, use flexible cable (stranded or solid) of AWG No. 28-22.

•Any excessive twisting or bending may
damage the device’s PCB. Please
handle the device with care.
•The device is not recommended to be
placed on low thermal conductive
surfaces. For example, plastics.
•Prevent any foreign metal, particles or
conductors from entering the device
through the openings during
installation. It may cause: -Electric
shock; Safety hazard; Product failure.
•The power supply must be mounted
by metal screws onto a grounded
metal surface. It is highly
recommended that the Earth
terminal on the connector be
connected to the grounded metal
surface.

Notes
1. Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region,
refer to the graphs shown above.
2. If the output capacity is not reduced when the surrounding air temperature is more than the upper limit temperature, the device will
run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the
surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition.
3. Depending on the surrounding air temperature and output load delivered by the power supply, the device housing can be very hot!
4. If the device has to be mounted in any other orientation, please contact [e-mail] for more details.

Remote ON/OFF Function
You can remotely control the power supply unit to turn
ON/OFF by using an external DC source. Follow the DC
power source voltage and current limiting defined in the
table below.

Notes
1. Remote ON/OFF circuits are isolated from input, output and PE.
2. Please check if the polarity of the wire connector is the same as the external DC source. If not, the power would not turn on and the
internal components may be damaged.
3. You do not need an external resistance ROfor current limit while the output voltage of external DC source is within the range of 5-
12.5V. If the output voltage exceeds 12.5V, please use the following equation for the value of current limit resistance RO.
