The Softstart module is used to minimize transformer inrush currents and provide for push button control at the same time.
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.
