    Gefran GTS40/48D-0 Việt Nam

    GTS 15/25/40/50/60/75/90/120A POWER SOLID STATE RELAYS WITH LOGIC CONTROL Vdc / Vac

     

    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, 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. ALARM OPTION: for models with AC control (Input type = “A”) 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) NOTE: in the absence of the control, the alarm output is always open (the alarm memory latch function is not possible, as with GTS with Type “D” input). Option function description: for models with DC control (Input type = “D”) The Alarm Output Function activates the output switch (or PNP digital output) when detects the following situations: • The control signal is ON, but there is not current in the Load (No Current, No Load condition) • The control signal is ON, but there is not GTS power Line voltage supply (No Line condition) • The control signal is ON, but the SCR / Heat sink is in overtemperature (GTS thermal protection condition) The alarm output is latched: its status it is maintained if the Control signal is switched off, the alarm output resets when the load current is restored or when the GTS 24V_supply is switched off and on (V_supply reset). The alarm output option is available as Insulated Solid State Switch (or as Digital Output PNP), with Normally open switch (or PNP normally non active) or normally closed switch (or PNP normally active) status.
