General Description
The new PMT series of panel mount power supplies is the latest offering from one of the world’s largest power supply manufacturers
and solution providers – Delta. The PMT products also offer a nominal output voltage of 5V with a wide operating temperature range
from -10°C to +70°C and can withstand shock and vibration requirements (in accordance to IEC 60068-2-27 and IEC 60068-2-6
respectively). In addition to features like overvoltage and overload protections, Delta’s PMT series of panel mount power supplies isunlike many other brands in the same price level. The PMT series is designed for cost competitive markets without compromising thequality of the components and product specifications. The series of products has an expected life time of 10 years and this versatile
product has three different connector options (Terminal Block and Front Face) and can also be converted into L Frame (PML) type ofpower supplies to satisfy different application needs.

Power supply components may degrade, or
be damaged, when the power supply iscontinuously used outside the shaded region,refer to the graph shown in Fig. 1.
If the output capacity is not reduced when thesurrounding air temperature >50°C, thedevice will run into Over Temperature
Protection. When activated, the output
voltage will go into bouncing mode and will
recoverwhenthesurrounding
airtemperature is lowered or the load is reduced
as far as necessary to keep the device inworking condition.
In order for the device to function in themanner intended, it is also necessary to keepa safety distance of 20mm with adjacent units
while the device is in operation.
Dependingon
thesurrounding
airtemperature and output load delivered by thepower supply, the device can be very hot!
If the device has to be mounted in any otherorientation, please do not hesitate to contact

If user’s mounting orientation is not according to the recommended mounting orientations, please consult Delta for furtherinformation.
L frame (PML) and Open frame (PMB) options are to be manufactured by Delta and not to be reconfigured by users from thestandard enclosed configuration.
The device is not recommended to be placed on low thermal conductive surface. For example, plastics.
The enclosure of the device can become very hot depending on the ambient temperature and load of the power supply. Do nottouch the device while it is in operation or immediately after power is turned OFF. Risk of burning!
Do not touch the terminals while power is being supplied. Risk of electric shock.
Prevent any foreign metal, particles or conductors from entering the device through the openings during installation.
It may cause electric shock, safety hazard, fire and/or product failure.
The power supply must be mounted by metal screws onto a grounded metal surface. It is highly recommended that the Earthterminal on the connector be connected to the grounded surface.
Warning (For Standard Terminal Block and Front Face Terminal Block products): When connecting the device, secure Earthconnection before connecting L and N. When disconnecting the device, remove L and N connections before removing the Earthconnection.

FunctionsStart-up TimeThe time required for the output voltage to reach 90% of its set value, after the input voltage is applied.

Rise TimeThe 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 timerequired for the output to reach 95% of its set value, after the input voltage is removed.

Graph illustrating the Start-up Time, Rise Time, and Hold-up Time

Inrush Current

Dynamic Response

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 peakvalue decreases exponentially during subsequent cycles of ACvoltage.

The power supply output voltage will remain within ±1000mVpp ofits steady state value, when subjected to a dynamic load from10 to 50% and 50 to 100% of its rated current.

Overload & Overcurrent Protections

Overvoltage Protection

The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated when output current exceeds 105%of IO (Max load). In such occurrence, the VO will start to droop andonce the power supply has reached its maximum power limit, theprotection is activated and the power supply will go into “Hiccupmode” (Auto-Recovery). The power supply will recover once thefault condition of the OLP and OCP is removed and I O is backwithin the specifications.

The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 3 under “Protections”.

Over Temperature Protection

It is not recommended to prolong the duration of Io when it is<105% but >100%, since it may cause damage to the PSU.

As mentioned above, the power supply also has Over
Temperature Protection (OTP). In the event of a higher operating
temperature at 100% load, the power supply will run into OTP
when the operating temperature is beyond what is recommended
in the de-rating graph. When activated, the output voltage will go
into bouncing mode until the temperature drops to its normal
operating temperature as recommended in the 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 current will operate in “Hiccup mode”, as shown in theillustration in the OLP/OCP section on this page. The power
supply will return to normal operation after the short circuit isremoved.

OthersDelta RoHS Compliant
Restriction of the usage of hazardous substances
The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical andelectronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances inelectrical and electronic equipment”.
This product conforms to this standard.
