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. 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 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 IO is back within the specifications. It is not recommended to prolong the duration of IO when it is 100%, since it may cause damage to the PSU. Overvoltage Protection (Latch Mode) Over Temperature 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 defined on Page 3 under “Protections”. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. 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. 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. 14 All parameters are specified at 25°C ambient and AC input unless otherwise indicated. www.DeltaPSU.com (April 2022, Rev. 11) TECHNICAL DATASHEET PJB Open Frame Power Supply 24 V 150 W 1 Phase / PJB-24V150W□□A Others 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.
