Product information

1Q transistor speed controller GS1/xx-294

The GS1/xx Series 1Q transistor controllers for single-phase connection 230V AC are compact, mains-connected speed controllers that can be used for armature and field supply of variable-speed DC drives with external or permanent excitation. The controller electronics can be operated with brushed DC motors, either by EMF evaluation with IxR compensation or with tachogenerators attached to the motor. The synchronized, pulse-modulated transistor regulators can be used in a wide range of applications thanks to their high efficiency and small size. The control parameters are adjusted to the respective applications using the potentiometers provided.

Features

For use with permanent and separately excited motors up to 0.75 kW motor power (armature voltage up to max. 200 V DC)
Precision speed controller with high control range up to 1:1000.
Subordinate current control circuit with adjustable current limit.
High pulse frequency of 18 kHz allows for a quiet operation.
Direct mains connection, no mains or smoothing chokes required.
Form factor F < 1.05 ensures low motor heating and high Md reserves.
Overloadable up to 200% peak current for max. 1 sec.
Blocking protection with overload cut-off.
