DIN Connector Form A PWM 11-89% Energy Saving 12-24vDC IP65

Description

DIN Connector Form A PWM 11-89% Energy Saving 12-24vDC IP65, Nass Magnet 611-201-0100

Form A EN 175301-803 12-24vDC Pulse Width Modulating energy saving electrical DIN connectors.

PWM connector will fully energise the valve solenoid to achieve full inrush current. Then, after approximately 150 milliseconds, the PWM circuit reduces the full current to a reliable holding power that needs to be adjusted using the 3-2–1 jumpers to the holding power required by the solenoid valve coil.

This achieves considerable energy saving, reduces coil heat rise and extends solenoid coil life.

PWM modulating connector jumper settings for the Hold Power Saving
000...11%, 001...22%, 010...33%, 011...44%, 100...56%, 101...67%, 110...78%, 111...89%

Simplified guide to setting up.
With the pipe system at full load / pressure, reduce the power in single stages until the coil fails to operate correctly, then go back one step.
Example starting with (000) 11% reduction, then (001) 22%, (010) 33%, (011) 44% and (100) 56%, then if coil stops holding so go back 1 step to (011) 44%.

The power reduction is accomplished through pulses with adjustable modulation via relocation of the electrical jumpers for changes in the output voltage. (default setting 11% reduction)

Operating voltage: 12-24vDC
Maximum current: 2.5 Amp
Resistance: <15mOhm
Protection: diode
Delay = ca. 150 ms
Switching Frequency = 3 kHz at 24vDC,
Pulse Ratio of PWM signal = 8 variations,

For optimum performance, the solenoid coil technical data and electrical parameters must be observed. The PWM circuit includes a protecting diode at the output, eliminating the switch off power surges from the solenoid coil.
Additional protecting components such as VDR and TVS diodes are not required.
