Description
HRP-300N3 series is a 300W single output AC/DC ultra-high peak power supply. This series operates at 85-264VAC input voltage and offers the models with the DC output mostly demanded from the industry. Each model is cooled by the built-in fan with fan ON-OFF control, working for the temperature up to 70C. Moreover, HRP-300N3 can provide 350% short-duration peak power for motor applications and electromechanical loads requiring much higher power during start-up.
