ABSOPULSE ELECTRONICS PFL 2K-E/110-F6W switching power supply is suitable for rugged 2kW industrial applications that require power factor correction (PFC). Unit uses field-proven PFQ 900 technology to deliver a compact, light-weight cost-effective solution with high system reliability and power efficiency. Product employs active power factor correction to convert 230Vac (195-264Vac) to an 110Vdc/18A single output. Custom input/output voltages are available on request. Device complies with EN61000-3-2 and EN61000‐3‐12 directives for low input harmonic distortion. Hold-up time is 5ms min at nominal input for 5% drop of the output voltage. An optional built-in redundancy diode allows parallel connection to achieve higher output power, N+1 redundant operation or back-up battery connection. Unit includes an output fail alarm, with Form C contacts available as an option.
