RR18
TSO'd REGULATED DC TO DC POWER CONVERTER
10-24Vdc to 24Vdc Regulated DC Power Converter
The RR18, converts a wide input voltage range of 10-24 Vdc to a dual regulated 24 Vdc outputs. The converter is capable of delivering 160 Watts and 25 watts continuously for an input voltage range of 10 to 24 Vdc. The converter delivers at full load a minimum voltage of 18 Vdc at 8 Vdc input voltage.
Control circuitry includes use of a popular PWM for voltage regulation and output current limit. Protection circuitry includes the output over-voltage limit.
