AC-DC Power supply offers 208Vac, 3-phase active PFC-input and up to 400Vdc output
3-phase AC-DC power supply with active PFC-input designed to meet the needs of heavy-duty 5kW industrial applications
The PFH 5K-A3P/XX-3U7 AC-DC Power Supplies with 3-phase active PFC-input are designed for heavy-duty, 5kW industrial applications. The units operate from a three-phase input of 208Vac (197-264Vac operating range) and deliver any single output from 24Vdc to 400Vdc. Other I/O values are available on request. A similar version that operates from 400Vac 3-phase sources are also available. Efficiency is typically 84% at full load, depending on the required input/output configuration.
Several PFH 5K-A3P/XX-3U7 power supplies can be configured in parallel to create a 10kW, 15kW, or higher DC-power solution.
The 3-phase AC-DC power supply is used to power industrial applications including as DC motor control, battery charging, DC bus voltage for distributed systems and power servos.
The 5kW AC-DC power supply system also functions as a redundant power supply, ensuring high reliability in critical applications. It is built with six PFH 65 internal modules that are connected parallel via internal redundancy diodes. This modular construction provides inherent redundancy; if one internal module fails, the system will remain operational at a lower output power.
The PFH 5K-A3P/XX-3U7 complies with EN61000-3-2 and EN61000‐3‐12 directives for low input harmonic distortion. Power Factor is better than 0.97 at full load for the entire input range. It is designed for compliance with EN62368-1 and equivalent safety standards. Filtering on the input and output contributes to low output ripple and noise. The input meets EN55032 Class A with wide margins; Class B is available as an option. Electronic protection includes 4300Vdc input-output isolation, inrush current limiting, output current limiting with short-circuit protection, output over-voltage protection and thermal shutdown with automatic reset in case of insufficient airflow.
High quality built-in fans provide sufficient cooling for operation over a 0°C to +50°C temperature range for full specification without derating. All heat generating components are installed on aluminium heatsink blocks which are thermally connected to the base plate.
The power supplies are ruggedized for immunity to shock and vibration. The internal boards are conformal coated for protection from moisture and airborne contaminants.
The 5kW 3-phase AC-DC power supplies are available in a 3U x 19” rack mount chassis (132 x 483 x 407mm) as well as a 3U chassis mount unit (132 x 432 x 407 mm).
