The following graph shows the overload detection and reset operation of the S8E3. Rated voltage Output current (%) Type Operating method Detection Reset V1 Inverted drop 105% min. of rated Automatically resets load current when the output current returns to normal V2, V3 Short-circuit protection --- Automatically resets when the output current returns to normal Note: 1. The overload protection function of output V is triggered when the total output of V , V , and V exceeds the permissible out- 1 1 2 3 put capacity of the S8E3 (total overcurrent protection). If outputs V and V are within their rated currents, overload protection 2 3 for V operates with its output current is 105% or more of the rated output current. Caution is required, however, because op- 1 eration depends on the output status of outputs V and V . 2 3 2. V2 and V3 have an independent short-circuit protection function. 3. Do not continue operating the S8E3 if an output terminal is short-circuited or overloaded, or the S8E3 may incur output voltage fluctuation, internal element deterioration, or damage. � OVERVOLTAGE PROTECTION (V1 OUTPUT ONLY) Overvoltage protection operating The Power Supply is provided with an overvoltage protection Approx. function that protects the load and the Power Supply from 20% possible damage by overvoltage. When the output voltage 5% rises above a set value (120% of the rated output voltage), Rated output the protection function is triggered, shutting off all of the Variable range voltage output voltage. If this occurs, reset the Power Supply by turning it off for 1 minute min. and then turning it on again. � INRUSH CURRENT, START UP TIME, HOLD TIME Input ON Input OFF AC input voltage Inrush current on input application AC input current 96.5% 90% Output voltage Start up time (100 ms max.)

The rated current of the S8E3-05031� is 1.5 A at 12 V. The peak load current of the S8E3-05031� is available at 12 V under the following conditions, in which case the waveform of the load current must satisfy the following formula. Time (s) (Ip – a)τ Iav � Im = + a (see note) T Ip: Peak current (2 A max.) (A) Iav: Rated output current (1.5 A) (A) Im: Mean load current (A) τ: Pulse width of peak current (30 s max.) (S) T: Frequency (S) a: Continuous load current (A) Note: When the output current rises above the peak current, the overload protection function is triggered and the output voltage will decrease. 5 Switching Power Supply S82K Load current (%) Dimensions Unit: mm (inch) � SWITCHING POWER SUPPLIES Front Terminal Models 30-W Models Two, M3 mounting holes 10 max.

The Power Supply is designed to dissipate heat through natural air-flow. Penetration of Metal Filings and Cuttings • Forced-air cooling is recommended. If drilling and other work is carried out over the power supply, metal filings, cuttings, and other materials may fall onto the Two (or More) Power Supplies Mounted Side-by-Side printed circuit boards inside the power supply, leading to internal When mounting two or more Power Supplies side-by-side, allow shorts and damage. If it is necessary to work over top of the at least 20 mm spacing between them, as shown in the following power supply, cover the power supply with a sheet or other illustration. suitable material to prevent the entry of foreign matter into the power supply. This step is necessary even if the power supply is equipped with a cover. After completing the above work and before supplying power, remove the sheet to avoid interference with appropriate cooling. 20 mm min. ������ !"���"���#�$"��%!��"� ���� !&!%���&�����’��������������(�����������()���’�����*�+,�- ��������������������� ������������������ ������������� ����������������’� 22,� �������’��3� ����������������������������� ����3��3�7)�����/489 &������)��������� 45�,62 ������������������������������ ������������ ���������������������������� ������������ 1����������������(3�����������������:3����(� ������������ Cat No. GC PS6 2/03 Specifications subject to change without notice Printed in USA 8 Switching Power Supply S8E3
