Product Description

The Kollmorgen 65WKS-M310/12-PB is an analog servo amplifier. It is designed for 3-phase AC input at 80 to 220 Volts AC. The installed load at rated current for the amplifier is 2.6 kVA. The DC-link voltage rating is 310 Volts DC. The continuous rated 4-quadrant output current is 12 Amps. The peak output current is 30 Amps. The maximum AC fuse size recommended for use with the 65WKS-M310/12-PB is 30 Amps. The switch-on threshold of the ballast circuit is 385 Volts and the switch-off threshold of the ballast circuit is 365 Volts. The pulse power of the ballast circuit is 5.4 kilowatts and the continuous power is 200 Watts.  The overvoltage switch-off threshold is 410 Volts. The minimum motor inductance is 3 millihenry. Clock frequency of the output stage is 1 kilohertz.

The quiescent dissipation for the 65WKS-M310/12-PB with the output stage disabled is 12 Watts. Heat dissipation of the amplifier including power supply unit is 90 Watts. Connection terminals for the power leads are available on the backplane board of the 65WKS-M310/12-PB. Weight and dimensions of the 65WKS-M310/12-PB system are 2 kilograms and 220 x 233 x 60 millimeters respectively. The servo amplifier is designed for driving brushless servo motors belonging to the SMR series. The servo amplifier can be used for speed or torque control. Power to the 65WKS-M310/12-PB needs to be supplied through an isolating transformer from an industrial three-phase supply. The amplifier is not suitable for continuous braking operation. it is designed for indoor use and should be mounted inside a steel switchgear cabinet. The recommended temperature range for amplifier operation is from 0 to 45 degrees Celsius at rated data.
