The Allen-Bradley 25A-E6P6N104 PowerFlex 523 Adjustable Frequency AC Drive is a variable AC frequency drive, designed for control of 3-phase induction motors, and it is suitable for standalone industrial applications. The 25A-E6P6N104 has compact design for easy installation, a selectable motor controls feature, an energy saving feature, and easy programming, and it has digital motor control which ensures precise operation and repeatability. Its drive rating is 6.6A, and 4.0kW (5.0HP), with an operating line input voltage of 600V AC (3-phase) at 50/60Hz, and its input tolerance range is -15% to +10% at 47 to 63Hz. The 25A-E6P6N104 provides full ratings on all 3-phase power, and its displacement power factor is 0.98 across the entire speed range, with a 97.5% drive efficiency. It has a maximum short-circuit rating of 100,000A, with AC BUS overvoltage and under voltage trips of 711V AC and 344V AC on the incoming line, and it has a microprocessor-controlled overcurrent trip with a 200% limit for hardware and a 300%% for instantaneous fault. The 25A-E6P6N104 has a robust power ride-through time of 100ms, with a Logicride-through time of 2s, and it provides Phase-to-Phase and Phase-to-Ground protection using the installed Metal Oxide Varistor (MOV). It provides excellent motor control using either the standard Volt per Hertz (V/Hz) control, or the Sensorless Vector control, or the Sensorless Vector control with an economizer, and it uses a Sine-coded Pulse Width Modulated Signal with a programmable carrier range of 2 to 16 KHz for output control.

The 25A-E6P6N104’s programmable control output frequency range is 0 to 500Hz, with a selectable output voltage range between 0 and the rated motor voltage, and it has a 97.5% control efficiency. It provides ±1% of the base speed regulation across a 60:1 speed range using the standard Volt per Hertz control, with ±0.5% of the base speed regulation across a 100:1 speed range using the Sensorless Vector control, and it provides ±0.5% of the base speed regulation across a 100:1 speed range using the Sensorless Vector control with an economizer. The 25A-E6P6N104 has 5 digital inputs with 24V DC control selectable between Source or Sink control via DIP switch, 1 Analog Unipolar Voltage or a current input, 1 programmable Form C Relay outputs, and a 10-bit, 0 to 10V DC or 4 to 20mA Analog output. The 25A-E6P6N104 has an integral multi-language HIM module with a descriptive QuickView scrolling text for easy configuration, and it has an integral RS-485 communication port, and an optional Dual-port EtherNet/IP communication card. It is a Frame B drive with the Standard baking option, and it is enclosed in an Open Type (IP20) rated enclosure. Its operating temperature range is -4 to 122 °F, at 5 to 95% non-condensing humidity, and it is made to operate a height of 1,000m without de-rating. The 25A-E6P6N104 weighs approximately 1.6Kg, with net dimensions of 87.0mm x 180.0mm x 172.0mm, and it is cUL-us, RCM, CE, TUV, ATEX, KCC, and RoHS certified.
