Note:
1 Refer to Output Voltage Adjustment for S8TS-06024[]on datasheet.
2 The output specifications are defined at power output terminals.
3 Specified by performance of S8TS-06024[] Basic Block.
4 Specified by S8TS-06024[] connection.
5 The output voltage will be 21.0 V (min.) when switching to backup operation.
6 Refer to Backup Time (Reference Value) on datasheet.
7 Refer to Functions on datasheet for details.
8 Set the detection current to 20 mA × N, where N is the number of S8TS-06024[] Basic Blocks connected.
9 Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.
10 To ensure Class 2, take one of following measures.
Note that the number of S8TS-06024[] to be connected to the S8T-DCBU-01 shall be one.
Connect S8T-DCBU-01 to S82Y-TS01 having its fuse replaced with an UL-Listed and DC rated 32 VDC min./ 3 A max. one.
Connect an UL-Listed and DC rated 32 VDC min./ 2.5 A max. fuse at the location shown in Fig.1.
