CO3301-5G
Exciter voltage regulator CO3301-5G is used to supply excitation voltage to synchronous machines such
as SE2662-5Q (three-phase synchronous machine with a smooth-core rotor, 1 kW). The direct voltage
can be adjusted in the 7.5 ... 200 VDC range via a rotary control or inputs. During power-down, the
voltage is switched off, and a resistor connected in parallel to the outputs via a relay in order to de-
excite the machine.

CO3636-6W / CO2663-6U
The servo-machine test bench is a complete testing system for examining electrical machines and
drives. It consists of a digital controller, a brake and the ActiveServo software. The system
combines state-of-the-art technology with ease of operation.
The system also allows manual and automated synchronization to be carried out.

The controller has the following features:
1. Dynamic and static four-quadrant operation
2. 10 selectable operating modes/machine models (torque control, speed control, flywheel,
lifting drive, roller, fan, compressor, winding gear, arbitrarily defined time-dependent load,
manual and automated network synchronization)
3. Integrated galvanically isolated amplifier for voltage and current measurement Speed and
torque displays
4. A four-quadrant monitor
5. USB interface

11. Weight: 14.3 kg
The brake is self-cooled asynchronous servo-brake with a resolver.
The motor and sensor leads are connected via polarity-safe plugs. The machine has thermal
monitoring and, in conjunction with the controller, it constitutes a driving and braking system
that is free of drift and requires no calibration.

ActiveServo Program
ActiveServo is a program for recording characteristics of machines and for determining dynamic and
static operating points. It emulates seven different loads (flywheel, pump, lifting drive,
compressor, winding gear, arbitrarily configurable time-dependent load) for which the parameters
can be individually configured.

CO5127-1S
The three-phase power quality meter permits measurement and display of all relevant grid
parameters. It is able to carry out single, two-phase or three-phase measurements. Display and
operation are performed via menu navigation with an LC display or the integrated Ethernet interface.
The optional SCADA software provides for the display of all readings and allows implementation and
analysis of intelligent power grids (smart grid). The “Smart Meter” acts as a digital electricity meter at
the end points of the electricity grid to measure electricity consumption and can be used to turn
consumers on or off depending on circumstances.
