General Descrip ti o n
The PJB series of Open Frame Po wer Supply comes with uni versal AC i nput at 85Vac to 264V ac. Other f eatures inc lude lo w leakage /
Inrush current and conf ormal coatin g on the PCBAs to provide protection agains t dust and chemical pol lutants. 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 po wer to be al ways available for rel iable startup of loa ds with high inrush cur rent, thus eliminati ng the
need of a more expensiv e power suppl y unit at higher po wer rating. Met al chassis and case c over are availab le as options for different
installation preferences.
The PJB series is certified for EMI standards ac cording to EN 550 22 and EMS according t o EN 55024. The products conf orm to major
international safety standards according to EN/UL 60950-1 standards and are fully compliant with RoHS Directive 2011/65/EU for

1. Power supply components may degrade, or be damaged, when the power supply is continuously used outside t he shaded region,
refer to the graphs shown above.
2. If t he output capacity is not reduce d when the surrounding air temperature is more than t he upper limit temperatur e, the device will
run into Over Tem perature Protection. When activated, the output voltage will go i nto bouncing mode and will recover when the
surrounding air temperature is lowered or the load i s reduced as far as necessary to keep the device in working condition.
3. Depend ing on the surrounding air temperature and output load delivered by the power supply, the device housing can be very hot!

Start-up Time
The time required for the output voltage to reach 90% of its set value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its set value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 95% of its s et value, after the input v ol tage is removed.

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. T he 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
calculatio n below.

Inrush Current
Inrush current is the peak , instantan eous, input current mea sured
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 Protectio n
The power supply’s overvoltage circuit will be activated when its
internal feed back circuit fails. The output voltage shall n ot exceed
its specifications defined on Page 3 under “Protections”.
The power supply should be latch.
Overload & Overcurrent Protection s
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 VO will start to droop and
once the po wer supply has re ached its maximum power lim it, 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 IO is back
within the specifications.
It is not recommended to prolong the duration of IO when it is
<220% but >100%, since it may cause dam age to the PSU.
Over Temperature P rotection
As mentioned above, the power supply also has Over
Temperature P rotection (OTP). In the ev ent of a higher operating
temperature at 100% load, the power supply will run into OTP
when the oper ating temperature i s beyond what is r ecommended
in the de-rating graph. When activated, the output voltage wi ll go
into latch mode until the mains is reapplied and the temperature
drops to its nor mal op erat in g tem per atur e as recom me nde d in th e
de-rating graph.
Short Circuit Protection
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied,
the output curr ent will operate in “Hiccup mode”, as sho wn 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.

Restriction of the usage of hazardous substances
The European dir ective 2011/65/E U limits the maximum impurit y level of homogeneous mat erials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and
electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in
electrical and electronic equipment”.
This product conforms to this standard.
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 r eaching cir cuit nodes, wher e the mater ial slumps aro und shar p edges. T his c an be a problem
especially in highly co nv ersing atmosphere.
PFC – Norm EN 61000-3-2
Line Current Harmonic conte n t
Typically, the input curr ent waveform is n ot sinus odial due to the peri odic al peak chargi ng of the input capac itor.
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.
