Frequently Asked Questions
What is the operating ambient temperature range?
The unit operates in an ambient temperature range of 0°C to +70 °C.
How is max continuous output power affected by airflow?
For full power (250W), it requires 250 LFM forced air; otherwise, convection cooling limits the power and requires consulting the derating curve.
What are the standard input voltage requirements?
The unit accepts a universal input voltage range of 85-264 Vac, with an input frequency range of 47-63 Hz.
Does it offer protection against various electrical faults?
Yes, it includes overcurrent, overvoltage, and overtemperature protection, along with short circuit and ground leakage protection.
