[. . . ] To meet Class-2 requirements with the 100-W, either a fuse or circuit breaker that is UL listed or CSA certified, and rated at 4. 2 A max. should be wired in series with the load to be connected to the Power Supply. Only then can the Power Supply output be considered as meeting Class 2.

Ambient temperature (°C) Note that the derating curve may vary depending on the installation conditions. Multiple units cannot be installed in a configuration where they are lined up vertically. Use the 7. 5-W single-output models under the load of 90% max. if the voltage range is between 90 and 110 VDC. The cold-start time will be longer when using S82K-P09024 or S82K-P10024 with 85-VAC input. Mounting Top Top Note: Installations other than (A) and (B) are not possible.

When the output current rises above 105% min. of the rated current, the protection function is triggered, automatically decreasing the output voltage. When the output current falls within the rated range, the overload protection function is automatically cleared. 3-/7. 5/15 W Models Output voltage (V) 30-/50 W Models Output voltage (V) 90-/100 W Models Output voltage (V) Intermittent operation 0 50 100 Output current (%) 0 50 100 Output current (%) 0 50 100 Output current (%) Note: 1. When connecting a load that has a built-in DC-DC converter, the overcurrent protection function may operate during start-up, thus preventing the Power Supply from starting. Internal parts may occasionally deteriorate or be damaged if a short-circuited or other overcurrent state continues during operation. When using the 7. 5-W single-output models within the input voltage range between 90 and 110 VDC, the overload protection function will operate at currents from 95% to 160% of the rated output current. When using the 90-W model at an ambient temperature of 25°C or less, the overload protection function will operate at currents from 101% to 111% of the rated output current. When using the 90-W model at an ambient temperature exceeding 25°C, the overload protection function will operate at currents from 92% to 111% of the rated output current. When using the 100-W model with PFC in parallel operation, operation is limited to a load ratio of 90% to 100% of the rated output current at 4. 2 A. When Using ± Output Models The +V output detects the total output power (+V output and -V output) to trigger the short-circuit protection against overcurrent. This protection varies depending on the -V output state. [. . . ] In this case, the rated current per S82KP10024 is 3. 78 A. Incorrect 3-, 7. 5-, 15-, 30-, 50-W Models +V INPUT -V Incorrect 3-, 7. 5-, 15-, 30-, 50- and 90-W Models +V INPUT -V +V INPUT -V INPUT -V +V Parallel Operation Precautions The length and thickness of each wire connected to the load must be the same so that there is no difference in voltage drop value between the load and the output terminals of each Power Supply. Adjust the output voltage of each Power Supply so that there will be no difference in output voltage between each Power Supply. Wiring Do not apply more than 75-N force to the terminal block when tightening it. Ensure that input and output terminals are wired correctly. Minimum Output Current (S82K-00727/S82K-00728) The minimum output current of the S82K-00727 and S82K-00728 is restricted by the output voltage and control method. Note: All the outputs of the S82K-00727 and S82K-00728 are controlled by the +V output. [. . . ]
