Electric power saver TYPE:EES24V2/0.5A This electric power saver supplies full power to the solenoid for a pre-defined time then the voltage is lowered to a certain percentage of the input. That value can be 50%Vn, 33%Vn, 25%Vn according to the selected configuration. This value is then maintained throughout the time until the supply voltage is turned off. When the system is reset the cycle starts again. General dimensions The circuit is used in those applications where the force in the beginning of the stroke of a solenoid of 100% duty cycle is not enough or in applications where less heating of the solenoid is required. If a 24V supply is applied through the power saver to a 12VDC 100% duty-cycle solenoid, it will have a force equivalent to a duty-cycle of 25% while switching the solenoid. Voltage input: (C) Let unfed (+) Positive input of 24VDC ( -) Of input feed VALVE Connection to solenoid Products that can be applied Timing diagram Coil Voltage V supply * Before purchasing ask NAFSA’s technical department, because the coils usually need to be adjusted for the coordinated work between the solenoid and the electronic plate. Supply options: Option1 (O1): Electronic plate individually Option 2 (O2): Board integrated in the in a wiring subset and protected by thermoretractable cover. Connection to the power supply NAFSA reserves the right to any modification Power supply: 5 to 27VDC Maximum pull in current: 2A Maximum hold current: 0.5A Pull in time: 0.3 seconds Possible voltage reduction ratio:There are three versions to 50% Vn, 33%Vn or 25%Vn Operating temperature range: 0ºC to 50ºC Protection against reverse feed: -30VDC Protection against coil discharge through diode. Red lead: +Vdc Black lead: -Vdc Unless other specification it will be supplied with L1 and L2=300mm Option3 (O3): The electronic board integrated in a wiring subset and encapsulated by epoxy resin overmolded. NOTE: The supply option 3 (O3) will only be available for orders which require a minimum quantity defined by the commercial department of NAFSA Ordering code: Standard voltage reduced to 25%, supply option 1: Reference: EES24V2/0.5A25%O1 Standard voltage reduced to 33%, supply option 2 and default lenght of cables: Reference: EES24V2/0.5A33%O2 Standard voltage reduced to 50%, supply option 3 and cable lenght 500mm for L1 and 250mm for L2: Reference: EES24V2/0.5A50%O3-L1:500-L2:250
