7.6.2DB Resistors

1)Internal DB Resistor

SV-ACtionMaster inverters up to 3.7kW have built-in DB resistor on Power stack as factory installation. Installing the external DB resistor (Optional) kit is strongly recommended when the unit is used for continuous operation or motor rating is above 3.7kW.

Voltage		Applied motor	Operating rate	Built in DB resistor
		capacity (kW/HP)	(%ED/Continuous Braking Time)	(Braking Torque: 100%)
	0.75 / 1		3%/ 5Sec	200 ohm, 100W
200V Class	1.5 / 2		3% / 5 Sec	100 ohm, 100W
	2.2 / 3		2% / 5 Sec	60 ohm, 100W
	3.7 / 5		2% / 5 Sec	40 ohm, 100W
	0.75 / 1		3% / 5 Sec	900 ohm, 100W
400V Class	1.5 / 2		3% / 5 Sec	450 ohm, 100W
	2.2 / 3		2% / 5 Sec	300 ohm, 100W
	3.7 / 5		2% / 5 Sec	200 ohm, 100W

2) DB Resistor (For External Installation, Optional)

DB transistor is integrated for ratings below 7.5kW. Install the external DB resistor if necessary. However, DB transistor is not provided for the ratings above 11kW, installing both external DB unit and DB resistor are required. See the following table for more details (ED: 5%, Continuous Braking Time:15 sec). If Enable duty (%ED) is increased to 10%, use the external DB resistor having twice Wattage rating.
