DC/DC Converter VRB_LD-15WR3 Series 15W,Ultra wide input, isolated & regulated dual / single output DC/DC converter Wide range of input voltage (2:1) High efficiency up to 90% No-load power consumption as low as 0.12W Isolation voltage :1500VDC Input under-voltage protection, output short circuit, over-current, over–voltage protection Operating temperature range: -40℃ to +85℃ Meet CISPR22/EN55022 CLASS A Six-sided metal shielding package Reverse voltage protection available with A2S(Chassis mounting) or A4S(DIN-Rail mounting) IEC60950, UL60950, EN60950 approval VRB_LD-15WR3 series are applied to wide voltage range input situation, such as data transmission equipment, battery-operated device, battery power supply device, tele-comunication device, distributed power system, remote control system, industrial robot system etc. Selection Guide Input Voltage (VDC) Certification Output Current (mA)(Max./Min.) Nominal (Range) Efficiency (%,Min./ Typ.) @ Full Load Notes：①Series with suffix “H” are heat sink mounting; series with suffix “A2S” are chassis mounting，with suffix “A4S” are DIN-Rail mounting, for example URB2405LD-20WHR3A2S is of chassis mounting package with heat sink,URB2405LD-20WR3A4S is of DIN-Rail mounting without heat sink; If the application has a higher requirement for heat dissipation, we recommend modules with heat sink; ②Absolute maximum rating without damage on the converter, but it isn't recommended; ③Efficiency is measured In nominal input voltage and rated output load;A2S (wiring) and A4S (rail) Model due to input reverse polarity protection, minimum efficiency greater than Min.-2 is qualified; Input Specifications Item Operating Conditions Input Current (full load / no-load) Reflected Ripple Current Input impulse Voltage (1sec. max.)
