为不间断运行而设计
Powersoft has always been very focused on energy saving and the use of the Power Factor Correction (PFC) has been a trademark for improving performance and containing mains current draw and consumption.
In any amplifier output stage, the efficiency is a function of the difference in the output voltage delivered to the load and the rails voltage delivered from the power supply.

特点
- Universal switch mode power supply up to 400V AC tolerant with Power Factor Correction
- Patented output filter with ripple cancellation network
- Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
- Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket
- Ac protection: shut down power supply when AC mains voltage is outside operating range
- Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
- DC protection: protects against infrasonic signal at the outputs
- VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
- Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
- Long term limiter: protects the loudspeaker against steady long term RMS (non audio) signals, by reducing maximum output
- Thermal protection: output stages operating temperature up to 80 °C (176 °F)
- Temperature controlled continuous variable speed fan, front to back airflow
- Fixed frequency switch mode output stage for high grade sound accuracy
- All models 2 RU for reduced rack cost and space
- Light weight - for easier racking and shipping: 14 kg / 30.8 lbs
