pharmaceutical industry
• Industrial electric furnaces
• Food processing plants
GENERAL
Turning an electric load on or off
requires the use of a suitable
interrupt and protection device that is
safe and immune to disturbances.
In addition, for optimum process
control in many industrial
applications, it is indispensable to
drive the load with very short
switching times: the best solution is
the use of solid state relays.
Gefran proposes the GTS range of
power solid state relays with voltage
zero crossing, currents from 10A to
120A, and rated voltages of 230VAC
and 480VAC.
Versions with TRIAC and with double
SCR are available.
All models are designed to
guarantee operation at rated
currents, with continuous driving of
power at 40°C working temperature.
For less critical operating
conditions, you can use the
products beyond rated currents
(using the dissipation curves as
reference).
Various accessories are available,
such as the attachment for panel
fastening, fuses and fuse holders.
