DC/DC Converter wide input VRB24_LD-50WR3 - 1

DC/DC ConverterVRB24_LD-50W(H)R3(A2S/A4S) Series 50W isolated DC-DC converter in DIP packaging Wide input and regulated single output Patent Protection RoHS FEATURES • Wide 2:1 input voltage range • High efficiency up to 91% • I/O isolation test voltage 1.5K VDC • Input under-voltage protection, output short-circuit, over-current, over-voltage protection • Operating ambient temperature range: -40°C to +105 °C • No-load power consumption as low as 0.048W • Six-sided metal shielding package • Input reverse polarity protection available with chassis (A2S) or DIN-Rail mounting (A4S) version • Industry standard pin-out • Meets IEC62368, UL62368 standards • EN62368 approved VRB24_LD-50W(H)R3(A2S/A4S) series of isolated 50W DC-DC converter products with a wide 2:1 input voltage range. They feature efficiencies up to 9i%, input to output isolation is tested with 1500VDC and the converter safety operate ambient temperature of-40°C to +105 C, input under-voltage protection, output over-vo/tage, over-current., short-circuit protection. They are ideally and widely used in applications such as industrial control., electric power, instruments and communications. Notes: ©Use "H" suffix for heat sink mounting, "A2S" suffix for chassis mounting and "A4S" suffix for DIN-Rail mounting. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; ©The minimum input voltage and starting voltage of A2S and A4S Model are 1VDC higher than those of DIP package due to input reverse polarity protection function; ©Exceeding the maximum input voltage may cause permanent damage; ©Efficiency is measured at nominal input voltage and rated output load; efficiencies for A2S and A4S Model's is decreased by 2% due to the input reverse polarity protection circuit.

DC/DC ConverterVRB24_LD-50W(H)R3(A2S/A4S) Series Mechanical Specifications Design Reference 1. Typical application All DC-DC converters of this series are tested before delivery using the recommended circuit shown in Fig. 2. Input and/or output ripple can be further reduced by appropriately increasing the input & output capacitor values Cin and Cout and/or by selecting capacitors with a low ESR (equivalent series resistance). Also make sure that the capacitance is not exceeding the specified max. capacitive load value of the product. MORNSUN Guangzhou Science & Technology Co., Ltd....
