- Page 25 NOTES: USE WITH INDUCTIVE LOADS AND TRANSFORMERS a) Connect a varistor (MOV) between each wire of the primary transformer and ground. Varistor data: rated voltage 660Vrms,…, 1000Vrms; minimum energy 100J b) The maximum current controllable by the device is less than the product’s rated value (see technical data). c) In ZC and BF trigger mode, use the Delay-triggering function to limit peak magnetization current.
- Page 26 Figure 37 parameter defines the minimum number of conduction cycles settable from 1 to 10. In the following example, the parameter = 2. HSC - Half single cycle This mode corresponds to Burst Firing that manages ON and OFF half-cycles. NB: This mode is NOT allowed with inductive loads (transformers).
- Page 27 ADDITIONAL FUNCTIONS Softstart This type of start can be enabled either in phase control or pulse train mode and in zero-crossing mode (ZC, BF, HSC). In phase control, the increment of conduction angle q stops at the corresponding value of the power to be transferred to the load.
- Page 28 DT - “Delay triggering” (for ZC, BF control modes only) Settable from 0° to 90°. Useful for inductive loads (transformer primaries) to prevent current peak that in certain cases could trip the high-speed fuses that protect the SCRs.
