Description
Nass Magnet PWM Energy Saving DIN Connector 12–24V DC – 611-201-0100
The Nass Magnet 611-201-0100 is an intelligent PWM energy-saving DIN Form A connector designed to reduce the electrical holding power and heat generated by compatible 12–24V DC solenoid coils.
The connector initially supplies full power to the solenoid coil to provide reliable valve pull-in. After approximately 150 milliseconds, its integrated Pulse Width Modulation (PWM) circuit reduces the power supplied to the coil to an adjustable holding level.
Eight jumper-selectable PWM settings provide 11% to 89% power reduction, allowing the holding power to be matched to the requirements of the solenoid valve.
Reducing unnecessary holding power can significantly reduce solenoid coil temperature and electrical energy consumption, while potentially extending coil service life in continuously energised applications.

PWM Energy Saving Operation
A solenoid valve normally requires considerably more electrical power to initially move its armature than it requires to hold the valve in the energised position.
The 611-201-0100 takes advantage of this difference.
When first energised, the connector supplies full power to the solenoid coil to provide reliable pull-in.
After approximately 150ms, the internal PWM circuit automatically changes to reduced-power operation.
Instead of continuously applying full coil power, the connector rapidly pulses the electrical supply. The duty cycle determines the average power supplied to the coil.
The result is substantially lower electrical consumption and reduced heat generation while maintaining sufficient power to hold the valve energised.
Adjustable Energy Saving – 11% to 89%
Three internal jumpers provide eight selectable PWM power-reduction settings.
Jumper Setting → Power Reduction
000 → 11%
001 → 22%
010 → 33%
011 → 44%
100 → 56%
101 → 67%
110 → 78%
111 → 89%
Simplified Setup Guide
The optimum setting depends upon the electrical characteristics of the solenoid coil and the operating conditions of the valve.
A practical setup method is to operate the valve under its maximum expected pressure/load conditions and progressively increase the power reduction.
Start with the lowest reduction and increase one stage at a time:
11% → 22% → 33% → 44% → 56% → 67% → 78% → 89%
If the solenoid can no longer reliably remain energised at a particular setting, return to the previous reliable setting.
For example, if the valve operates reliably at 44% reduction but fails to hold correctly at 56% reduction, return to the 44% setting.
Adequate safety margin should always be maintained to account for changes in supply voltage, coil temperature and operating conditions.
Why Reduce Solenoid Coil Holding Power?
A conventional continuously energised solenoid coil consumes its rated electrical power for as long as it remains energised.
Much of that energy ultimately becomes heat.
Once a solenoid has pulled in, however, considerably less magnetic force may be required to hold the armature in position.
Reducing the holding power can therefore provide several advantages:
✓ Lower electrical energy consumption
✓ Reduced solenoid coil temperature
✓ Less heat transferred into the valve
✓ Reduced heat within control enclosures
✓ Potentially longer coil service life
✓ Improved efficiency for continuously energised valves
The greatest benefits are therefore likely to be found on valves that remain energised for long periods rather than applications that switch only briefly.

Important – Polarity Sensitive
Unlike many basic DIN connectors, the PWM electronic circuit is polarity sensitive.

Particularly Useful for Continuously Energised Valves
Why spend £35 rather than £1–£5 on a conventional DIN connector?
If a valve operates only occasionally, the energy saving from a PWM connector may be relatively small.
Where a solenoid remains energised for hours at a time, however, reducing the holding power can considerably reduce both electrical consumption and coil heat generation.
This makes the 611-201-0100 particularly interesting for:
✓ Normally open valves held closed
✓ Valves energised throughout production shifts
✓ Battery-powered systems
✓ Multiple-solenoid installations
✓ Equipment where coil heat is undesirable
✓ Energy-efficiency improvement projects
✓ Significant Coil Heat reduction up to 65%
✓ Greatly reduced limescale buildup for hard water applications
Important Coil Selection
For optimum operation, the connected solenoid coil's electrical characteristics must be considered.
The lowest possible PWM holding power is not necessarily the best setting.
The selected power level must provide sufficient magnetic force to hold the solenoid reliably under worst-case operating conditions, including:
✓ Maximum working pressure
✓ Hot coil conditions
✓ Minimum permissible supply voltage
✓ Normal voltage fluctuations
✓ Mechanical tolerances
Reliability should take priority over achieving the maximum theoretical energy reduction.
