POWER SOLID STATE RELAYS WITH LOGIC CONTROL Vdc / Vac
Main 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)
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 over-tem­perature (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.

THERMAL PROTECTION
(only on GTS models with > 40A current):
The SCR module’s temperature is
constantly monitored inside the devi­ce. When the maximum temperature threshold (T=110°C) is exceeded, current flow to the load is interrupted and the condition is signaled by ligh­ting of the yellow thermal protection LED.

Rated isolation voltage input/output: 4000VAC rms
Ambient conditions
Working ambient temperature: da 0 a 80°C (according to dissipa­tion curves)
Max. relative humidity: 50% at 40°C
Max. installation altitude: 2000m asl
Pollution level : 2
Storage temperature: -20..+85°C
Installation notes
Use the high-speed fuse specified in the catalog according to the connec­tion example given.
- Applications with solid state power units must also include an automatic safety switch to cut out the load power line. For maximum reliability, it is essential to install the device correctly in the panel in order to have adequate heat exchange between the sink and the surrounding air by natural convection. Install the device vertically (max. 10° inclination to vertical axis)
• Vertical distance between a device and panel wall >100mm
• Horizontal distance between a devi­ce and panel wall: at least 20mm
• Vertical distance between one device and another: at least 300mm.
• Horizontal distance between one device and another: at least 20mm. Make sure that the cable channels do not reduce such distances; if so, install the groups cantilevered to the panel so that air can flow vertically on the heat sink without obstructions.
Limits of use
• dissipation of thermal power of devi­ce with restrictions on temperature of installation site.
• requires exchange with outside air or an air conditioner to transfer dissi­pated power outside the panel.
• installation restrictions (distances between devices to guarantee dissi­pation by natural convection)
• max. voltage limits and derivative of transients in line, for which the solid state unit has internal protection devi­ces (depending on model).
• presence of leakage current < 3mA. (max. value with rated voltage and junction temperature of 125°C).

WARNINGS
WARNING: this symbol indicates danger.
Read the following warnings before installing, connecting or using the device:
• follow instructions precisely when connecting the device.
• always use cables that are suitable for the voltage and current levels indicated in the technical specifications.
• In applications with risk of damage to persons, machines or materials, you MUST install auxiliary alarm devices.
It is advisable to verify frequently that the alarm device is functional even during the normal operation of the equipment.
• DO NOT operate the device in rooms with dangerous (inflammable or explosive) atmosphere.
• During continuous operation, the heat sink can reach up to 100°C, and stays at a high temperature even after the device is turned off due to thermal inertia; therefore, DO NOT touch it and avoid contact with electrical wires.
• do not work on the power part without first disconnecting electrical power to the panel.
• do not remove the cover when the device is powered!
Installation:
• correctly ground the device using the specific terminal.
• power supply lines must be separated from device input and output lines; always check that the supply voltage matches the voltage indicated on the device label.
• avoid dust, humidity, corrosive gases and heat sources.
• respect the installation distances between one device and another (to allow for dissipation of generated heat).
• to keep air in movement, we advise you to install a fan near the GTS group in the electrical panel containing the GTSs.
• respect the indicated dissipation curves Maintenance: at regular intervals, check operation of the cooling fans and clean all air ventilation filters.
• repairs must be done out only by trained and specialized personnel. Cut power to the device before accessing internal parts.
• do not clean the box with solvents derived from hydrocarbons (trichloroethylene, gasoline, etc.). Using such solvents will compromise the
device’s mechanical reliability. Use a clean cloth moistened with ethyl alcohol or water to clean external parts in plastic.
Service: GEFRAN has a service department. The warranty excludes defects caused by any use not conforming to these instructions.
GEFRAN spa reserves the right to make aesthetic or functional changes at any time and without notice.
