    Product details

    Hypex Softstart Module


    Transformer inrush current is limited by means of a triac switching heavy-duty resistors in series with AC mains prior to relay switching. With an optional (bi-color) LED the status “On” or “Standby” can be indicated. In “Standby” the power-consumption will be less than 1.2W. The Softstart can operate with either a push button or a switch (jumper selectable). If additional thermal protection is required, a PTC-option is selectable. The Softstart can switch multiple transformers up to a total maximum of 1500VA. Maximum continuous current must not exceed 6A.


    This module is designed as a toroidal transformer inrush current limiter. Although it is successfully used in combination with a SMPS, this has not been tested or approved by Hypex Electronics. As a service, in the datasheet, a connection diagram is given for the use of this module in combination with one SMPS400. Additional support on the use of this module in combination with SMPS cannot be given.

    • Push button control
    • Temperature monitoring
    • Single/dual LED indication

    Working perfect. The only thing
    is if I connect the Switch
    I need to put a relay in between the output from my processor that is NC activ after start, and the softstart is NO to be active.
