IRQ Series Encapsulated Quarter-Brick 100-Watt Isolated DC-DC Converter Output Voltage (V) Output Current (A) Input Voltage (V) 5 20 110 12 8.3 110 24 4.2 110 Optimized for harsh environments in industrial/railway applications, the IRQ DC-DC converter series offer regulated outputs in an industry-standard quarter brick fully encased package. FEATURES PRODUCT OVERVIEW DC input range: 57.6-160V The IRQ series regulated converter module The IRQs diode-rectifier topology and fixed (Covers both 96V and 110V input range) deliver a 5V, 12V or 24V output Vin = 57.6 frequency operations means excellent Encapsulated circuitry for optimal thermal/vibration efficiencies. A wealth of electronic protection 160 Vdc in an industry standard quarter performance brick fully encased package at astonishing features include input under voltage lockout, Regulation: 0.3% from no load to full load efficiency. The fully isolated (3000Vrms) IRQ output over voltage lockout protection, output current limit, short circuit hiccup, Vout High Efficiency series accept a 57.6 to 160 Volt DC input voltage range with a reinforced insulation overshoot, a nd over temperature shutdown. Maximum baseplate operating temperature: 100C, system. Typical applications include Available options include various pin lengths full load industrial, railway and transportation and flanged baseplate. The IRQ series is Over-current & Over-temperature protection applications. designed to meet all UL and IEC emissions, Diode rectifier topology safety, and flammability certifications.
