Faber‑Com MDB PWM Regulator (Model: PSCH55S)

Overview

The MDB PWM Regulator (PSCH55S) would likely be a multi‑channel PWM output module designed to control proportional solenoid valves in open‑loop hydraulic systems. It would accept analog input signals (e.g. 0–5 V or ratiometric) and output corresponding PWM drive currents to valve coils.

Typical Features & Functions

• Multiple PWM output channels (e.g. 2 / 4 / 8) for proportional valve control
• Analog input channels, one per PWM output
• Adjustable parameters:
   • Minimum (offset) and maximum (gain) coil currents
   • Rise / fall ramp times
   • PWM frequency (configurable)
• Enable / disable inputs or control logic
• Fault / status outputs
• Dump valve or bypass output, possibly shared across channels
• Compact module or card format with appropriate connector interface
• Protective features: overcurrent, short circuit, reverse polarity, ambient temperature compensation

Electrical / Mechanical Expectations

• Supply voltage range in the 10 – 30 V DC domain
• PWM current output capability in the range 0.1–2.5 A per channel (or per design)
• Configurable PWM frequency (common values: 50–300 Hz)
• Operating temperature range from –20 to +70 °C (or broader depending on variant)
• Compact form factor suited for panel or chassis mounting
• Connector or terminal interface for power, inputs, outputs, and control
