TT Electronics OPTEK Technology Develops IP65-rated High Voltage UL-Certified Optoisolator for ATEX/ICEex Applications
Carrollton, TX, - Providing power electronics design engineers with a high voltage optoisolator designed for use in harsh environments and explosion-proof applications, TT electronics OPTEK Technology has developed a UL- and VDE-rated optical isolator with 20KV isolation and 2Mbit/s data transmission rates designed to comply with ATEX and ICEex certifications for electrical equipment used in hazardous areas, as well as IP65 standards for environmental sealing. Designated the OPI1268S Series, the high speed optoisolator is designed for high voltage power isolation in applications requiring sealing against dust and liquids, as well as in electrical equipment in potentially explosive atmospheres, such as transportation systems, hybrid vehicles, medical devices, and industrial control/safety systems.
According to Rodney Bailey, vice president optoelectronic component solutions for TT electronics OPTEK Technology, the OPI1268S optoisolator is the only high voltage device on the market with this comprehensive range of certifications "Designed to carry a UL, VDE rating, ATEX/IECex certifications, and environmental sealing to IP65, the OPI1268S Series can be specified by our customers for a wide range of applications in potentially hazardous environments that require high voltage isolation."
The OPI1268S Series optoisolator is comprised of a high-efficiency GaAIAs (Gallium Aluminum Arsenide) LED with a peak wavelength of 850nm, optically coupled to a photodiode that detects incoming modulated light and converts it to a proportionate current. The device's high-gain linear amplifier is temperature-, current-, and voltage-compensated, resulting in a highly stable digital output with an open collector inverter configuration that delivers DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity with a data transfer rate of 2Mbits/s and a typical propagation delay (tPHL-tPLH) of ≤ 50ns.
The OPI1268S optoisolator also features a 6-axis load rating of 10GRMS, which is important for transportation applications.
The OPI1268S optoisolator's input diode exhibits a forward voltage of 1.8V (max) @IF = 20mA; with a continuous forward current of 50mA. Reverse current is 100µA (max) @VR = 2.0V. with reverse voltage of 3.0V. The output IC operates with 7V supply voltage with 40mW power dissipation.
Capable of isolating voltages up to 20kV, the OPI1268S Series also provides a voltage spike immunity of 30KV/µS dv/dt. Creepage distance/air path is 24mm. Operating temperature range is from -50°C to +100°C.
The OPI1268 device measures 27.94mm x 6.35mm x 8.89mm with a five-lead configuration (cathode, anode, Vcc, output and ground).
The OPI1268S Series optoisolators are UL-certified under file #E58730. Certifications for ATEX/ICEex and IP65 are pending.
