Description
The PAM-195-P-S3 is a power amplifier for proportional directional control valves with an integrated Leistungsbegrenzungsfunktion. Hier finden Sie eine Zusammenfassung der wichtigsten Eigenschaften und Funktionen:
- Order number: PAM-195-P-S3
- Function: Control of a directional control valve with two solenoids or a throttle valve with one solenoid.
- Power limiting: Integrated power limiting via an analogue input. The Power limiting can be used to limit the output power based on the measured pressure, or to limit the input/total power of several units.
- Control: Unipolar control with direction reversal or bipolar control via a differential input. Direction reversal for the second magnet via a switching input or scaling of the analogue setpoint input. Control via a simple unipolar signal (0–10 V) or a ±10 V differential signal.
- Output current: Regulated output current, independent of the power supply and the magnetic resistance. The output stage is monitored for cable breaks, is short-circuit-proof and switches off the power output stage in the event of a fault.
Parameterisation:
- Digitally reproducible settings.
- Simple and application-oriented parameterisation using WPC software.
- Free scaling of the analogue inputs.
- Free configuration of RAMP, MIN / MAX, output current and DITHER (frequency, amplitude).
- Characteristic curve linearisation using 10 XY points per direction.
- Output current range: 0.5… 2.6 A
- Cycle time: 0.125 ms for the magnetic current controller
- LED indicators: LEDs for displaying the operating status and faults.
- Fault diagnosis: Fault diagnosis and advanced functional testing.
- Communication: USB interface.
- Software: WPC-300 control programme (available on the manufacturer’s website).
Typical applications: Control of directional and throttle valves that require flexible adjustment. Control of all typical proportional valves from various manufacturers (BOSCH REXROTH,
PARKER, DUPLOMATIC, BUCHER…). Hydraulic applications in open or closed Control loop.
