Detailed Product Description

Motor Soft Starter

The HPS2DB series intelligent economic soft start is a highly sophisticated and reliable starter designed for use with standard three-phase, three-wire, squirrel cage induction motors. It provides the best method of reducing current and torque during motor starting.

The optional RS 485 Communication with MODBUS protocol enables full control

(Start, Stop, Dual Adjust, command, etc.) and supervision. Up to 32 starters can be connected

on a shield twisted pair to a host computer. 

   
Starting & Stopping :  
Prior to Installation
Check that Motor's Full Load Ampere is lower than or equal to the starters Full Load Current and that Main and Control voltages are as indicated on the front panel.

Mounting
The starter must be mounted vertically, allow sufficient space above and below the starter for suitable airflow.
Motor Starter

It is recommended to mount the starter directly on the rear metal plate for better heat dissipation.
Do not mount the starter near heat sources.
Protect the starter from dust and corrosive atmospheres.
Temp. Range and Heat Dissipation
The starter is rated to operate over a temperature range of -10ºC
(14ºF) to + 50ºC (122ºF). Relative noncondensed humidity inside the enclosure should not exceed 95%.
Starter's heat dissipation is approx. 3 x In (three times the current in watts).
Example: For a 100A motor, heat dissipation is approx. 300 watts.Internal enclosure heating can be reduced through the use of:
a. Additional ventilation
b. Employing a by-pass contactor.
Short Circuit Protection
Protect the starter against a short circuit by Thyristor Protection Fuses.
