Switch Mode Power Supply S82J 5
Note: 1. When a load is connected that has a built-in DC-DC converter, the overload protection may operate at startup and the power supply may
not start.
Refer to the Overload Protection section on page 10 for details.
2. Do not use the Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the
internal temperature of the Power Supply may result in ignition or burning.
3. Defined with a 100% load and the rated input voltage (100 or 200 VAC.)
4. The output specification is defined at the Power Supply output terminals.
5. If the V. ADJ adjuster is turned the voltage will increase by more than +10% of the voltage adjustment range.
When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.
6. Refer to the Overload Protection section on page 10 for details.
7. For resetting, turn OFF the power, leave for more than one minute, and then turn it ON again.
8. The protection-ON alarm indicator will light as soon as the output is interrupted. For resetting, turn OFF the input power, leave for more
than three minutes (90 seconds min. for the 300-W models), and then turn it back ON again.
9. Radiated emissions: The noise value is affected by factors such as the wiring method. For 300-W and 600-W models, use shielded wire
for all wiring, and insert one noise clamp filter (TDK, ZCAT3035-1330) on the input wire, and two noise clamp filters on the load wire.
10.The weight indicated is the weight of the open-frame type. (Includes the covers for 300-W and 600-W models)
11.Use with DC voltage input is beyond the conditions of approval or conformance to applicable safety standards.
