DC/DC Railway Converter TEN 20WIRH Series, 20 Watt Fully encapsulated 1x1.6 package 3000 VAC I/O isolation (reinforced) 4:1 input voltage range: 36 160 VDC EN 50155 and EN 61373 certified Internal class A EMI filter UL 62368-1 IEC 62368-1 -40C up to +75C without derating The TEN 20WIRH is a series of 20 watt railway-certified DC/DC converters with EN 45545-2 fire behavior reinforced I/O isolation for highest reliability in harsh environments. The proven Remote on/off function and certified design guarantees highest resistance against thermal shocks, moisture, mechanical shocks, and vibration. The TEN 20WIRH comes with ad- Undervoltage lockout (UVLO), ditional EN 62368-1 safety approvals for IT equipment and EN 45545-2 certifi- short-circuit protection (SCP), cation for fire behavior. Thanks to its favorable operating temperature range of overtemperature protection (OTP), and -40C to +75C without derating (depending on the model), the TEN 20WIRH overvoltage protection (OVP) presents a first choice for demanding applications. 3-year product warranty Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
