Product Description
Can be used on both DC/AC lines, power plant control, optimal as an uninterruptible power supply
[Features]
· Both DC line and AC line can be used as input power source.
· 80-370VDC (80-110VDC has a load factor of 80%).
· 85-265VAC (75-85VAC output current 60%, guaranteed for 20 seconds).
· Long life: Expected life of electrolytic capacitor 10 years (ambient temperature 40℃, load factor 50%, 24 hours operation *standard installation).
· High efficiency: 88% (at HMS150-24 100VAC input).
· 4% improvement over the conventional model (MS-11-24 84%).
· Miniaturization: 55% smaller in volume than existing MS series.
· Wide operating ambient temperature.
· Safety and peace of mind: The use of "safety terminals" with live parts covered ensures safety and prevents the terminal screws from falling off, preventing loss of screws.
