Available from Luso Electronics, the RCD20 is a series of dc-dc converters in a compact 1"x1" industry standard package that delivers up to 20W of output power. Provides high performance and reliability for rail and industrial applications. Other regions use only one converter to handle different supply voltages (24, 28, 36, 48, 72, 96, 110VDC), thus avoiding multiple input voltage models in the warehouse. These converters have 8-1 or 12:1 ultra-wide input voltage ranges of 9-75VDC and 14-160VDC, simplifying the design of system power levels.
The patented enhanced hold-up Function is designed to simplify the supply interruption and switch design as defined in en50155. The device's BUS pin provides a stable and fixed charging voltage, enabling any input voltage to use only a hold-up capacitor, and, in addition, reduces inrush current during startup. In general, a capacitor must be installed at the input in order to keep the device running through an interruption or conversion of the supply voltage. The capacitance and rated voltage of a capacitor vary according to the supply voltage used.
The series has over current protection, output short circuit protection, output over voltage protection, adjustable input under voltage locking, over temperature protection and other self-protection functions. Including single output and dual output 5VDC, 5.1 VDC, 12 VDC, 24 VDC, ±12 VDC, ±15VDC. These converters are rated OT4 and ST1 for EN 50155 by installing heat fins on the modules
The products are certified under IEC/EN/UL 62368-1, EN 50155 and EN 45545-2 standards (pending). The products are certified under IEC/EN/UL 62368-1, EN 50155 and EN 45545-2 standards (pending). In addition, the shock and vibration ratings conform to en61373 and mil-std-810f. Operating at altitudes up to 5000 m, operating ambient temperatures from -40 ° C to +105C and input voltage ranges from 12:1 make these converters suitable for any rugged, high-reliability application, including railway rolling stock and transport in harsh industrial environments. In addition, the shock and vibration ratings conform to en61373 and mil-std-810f.
