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.

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.

It is not recommended to prolong the duration of Power Boost to be longer than the specified duty cycle calculation, this may cause
damage to the PSU.
Power Boost is the reserve power available
constantly that allows reliable startup to
support sudden and short spike of loads with
high inrush current typically during turn on to
remove the need of more expensive higher
rated power supply unit. After the output has
reached its steady state set value, the power
supply can support surge loads with a higher
short-term power demand up to 200% of
maximum rated load (IO
Max), for a
maximum duration of 10
seconds. The
Power Boost is also available to repeatedly
basis with according to the condition of an
average (R.M.S) output power shall not
exceed continuous operating condition or
refer to duty cycle calculation below.

Inrush Current
Inrush current is the peak, instantaneous, input current measured
and, occurs when the input voltage is first applied. For AC input
voltages, the maximum peak value of inrush current will occur
during the first half cycle of the applied AC voltage. This peak value
decreases exponentially during subsequent cycles of AC voltage.
Overvoltage Protection (Latch Mode)
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications as described in “Protections” section. Power
supply will latch, and require removal/re-application of input AC
voltage in order to restart.
The power supply should be latch.
Short Circuit Protection (Auto-Recovery)
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied, the
output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power supply
will return to normal operation after the short circuit is removed.
Overload & Overcurrent Protections (Auto-Recovery)
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 220% of
IO(Max load). In such occurrence, the VOwill start to droop and
once the power supply has reached its maximum power limit, the
protection is activated and the power supply will go into “Hiccup
mode” (Auto-Recovery). The power supply will recover once the
fault condition of the OLP and OCP is removed and IOis back within
the specifications.
It is not recommended to prolong the duration of IOwhen it is
<220% but >100%, since it may cause damage to the PSU.
Over Temperature Protection (Latch Mode)
As described in load de-rating section, the power supply also has
Over Temperature Protection (OTP). In the event of a higher
operating temperature at 100% load; or, when the operating
temperature is beyond what is recommended in the de-rating
graph, the OTP circuit will be activated. When activated, power
supply will latch off, until the surrounding air temperature drops to
its normal operating temperature or the load is reduced as
recommended in the de-rating graph. Removal/re-application of
input AC voltage will then be required in order to restart.

Conformal Coating
The Protective Coating Technology
Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including under
device, and prevents leakage. The conformal coating dipping can be applied to PCBs or circuit board. The coating
preserves the performance of precision electronic primarily by preventing ionizable contaminants such as salt
from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem especially in
highly conversing atmosphere.
PFC – Norm EN 61000-3-2
Line Current Harmonic content
Typically, the input current waveform is not sinusodial due to the periodical peak charging of the input capacitor.
In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying to
this standard can have some technical drawbacks, such as lower efficiency as well as some commercial aspects
such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard, therefore, it is
important to know whether it is mandatory to meet this standard for a specific application.
