PM4Q Controller |
High Frequency Mosfet Controller with Regenerative Braking for Permanent Magnet Motors |
PM4Q is suitable for transpallet, cleaning machines, sweeps and small utility vehicles, fitted with DC Permanent Magnet Motors between 300W - 800W.
External direction contactors are not required with this unit. It is therefore possible to achieve static direction inversion and regenerative braking. |
 |
|
Technical Features:
- Supply Voltage 24V
- Maximum current: 70A - 90A
- Current Booster
- Switching Frequency: 8KHz
- LED & Console Diagnostics
- Protection IP54
- Safety in accordance with European Standards
- Dimensions: 210 x 140 x 48mm
|
General Features:
- Mosfet Technology - High frequency, noiseless switching providing low energy commutation and low voltage drop
- Static inversion and energy recuperation - Reduced maintenance - Higher reliability • Microprocessor Logic: safety and flexibility
- Regenerative Braking - Reduced braking distance - Lower commutator heating
- Speed control - The speed is stable in every condition (tolerance +/- 5%) especially on gradients or during accelerator pedal release
- Anti roll back - On the gradient full power is provided in order to avoid truck roll back • Alarms memory
- Faults diagnosis: using a flashing led and/or by means of a digital console • Digital calibration: simplifies the controller installation and/or substitution. Once the settings are stored in the console, data transfer from the console to the controller is quick, safe and easy • Adaptability and flexibility
- Protection against reverse battery polarity (internal relay) • Automatic speed regulation with energy recuperation • Digital setting through the console
- Internal hour meter displayed in the console • BDI • Chopper temperature shown in the console • Tester function in the console • Thermal protection
- Low battery protection • Serial Link • Settings: - acceleration, braking, max speed, current
Options:
- Electromechanical brake driver • Hourmeter • Electrovalve or pump contactor drivers
