Power Solid State Relays with Logic Control

Product Details:

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, 480Vac and 600Vac. All models are designed to guarantee operation at rated currents, with continuous driving of power at 40°C ambient 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.

Features:

• Control input from VDC/VAC logic signal
• Switching at voltage zero crossing
• LED power on indicator
• MOV protections (varistor)
• Fastening to DIN bar (standard), fastening to panel (optional)
• Option alarm output for interrupted load
• Integrated SCR thermal protection with LED signal (only for models with > 40A current)

Applications:

• Plastic extrusion lines and injection presses
• Packing and packaging machines
• Polymerization and production plants for synthetic fibers
• Rubber vulcanization plants
• Driers for ceramics and construction elements
• Chemical and pharmaceutical industry
• Industrial electric furnaces
• Food processing plants

Rated working voltage:

• 230Vac (max. range 24...280Vac)
• 480Vac (max. range 24...530Vac)
• 600Vac (max range 24 ... 660Vac)

Non-repetitive voltage:

• 500Vp for model with rated voltage 230Vac
• 1200Vp for model with rated voltage 480Vac
• 1400Vp for model with rated voltage 600Va

Operating Description:

• The alarm output option activates closing of an isolated contact when it detects the following fault conditions
• Control signal active but no current on load (zero current, interrupted load)
• Control signal active but no power line voltage (no line)
• Control signal active but SCR / heatsink is in overtemperature (GTS thermal protection)
