Product Description

Solid State Switches (ALL)

      Ruby make Solid State Contactors are designed for Spot/Resistance Welding M/Cs and is a Retrofit Electrical Unit to replace the electromechanical-conventional-contactors. These are Thyristorised AC switch units having a compact SCR-SCR AC Switch Driver specially developed for Switching Thyristors with low voltage control - DC control. Thyristor gate drive is taken from across the line voltage between Cathodes of the Back to Back Thyristors. The gate drive from the driver module is DC which ensures the switching of the Thyristors to actuate even the inductive loads of low power factor (P.F). Since the driver has optical isolation between the input (control DC) and the power source AC the gate supply to the Thyristors is controlled by input DC control even if the mains AC supply is switched on. In this retrofit unit the DC control input is obtained from the Contactor coil terminals supply through the foot switch i.e. 230 or 415Vac converting it in to a 24Vdc (part of the unit) to energizes the LED input of the Opto which is turn switch ON the Thyristor energizing the load.

The driver ensures full firing of the Thyristors guaranteeing the switching of loads fully eliminating the risk of transformer going in saturation because of partial or half switching of the switch. The DC Gate Drive from the Driver is of the order of 250mA to 1Amp depending on the selection of the driver i.e. 2XT (Phc) or 2XT-HC(Phc) based on the current ratings of the Thyristor used in the design of the switch. This system tacitly avoids the risk of blowing of fuse or the power device resulting in the high reliability of operation and long working life of the unit. These Retrofit Units are in the form of a Heat Sink on which all the parts are assembled and have the ease of mounting in the panels with out any electrical isolation pads. These units have the advantage of operation with out Noise, free from Vibrations, Arcing etc. unlike in case of conventional contactors. Additionally the remarkable advantage over the conventional contactor is

  • No loss of efficiency of the load
  • Instant switching
  • Multiple number of switchings per minute
  • No power loss
Since no make or break contacts-which effectively will reduce the Electrical Bill over a period in use and operation. The working life is almost infinite when used with in range of specifications. These units ensure that the machines will have no downtime for maintenance with the positive gain of unaffected production. These units are available with the voltage rating of 415V, 2 Phase and current of 10 to 1000 Amps. A unit to replace a 70Amp. Contactor has a size of 204x150x100mm and is available for On/Off control. The same unit can be used for power control with an additional manual control module which also can be supplied.

Power control for the same is also available with additional control module with control Transformer and a potentiometer to vary the voltage 0 to 100% to have the welding power adjustable.
