The Allen-Bradley 1336VT-B025-EAP-FA2-L2 Adjustable Frequency Drive is a microprocessor-based high-performance variable frequency drive, used for the control of 3-phase induction motors in industrial applications where precise control of the motor speed is required. The drive has a digitally closed setup, control, and operation to ensure precise and repeatable drive control and operation, and the drive provides 3-phase industrial motors with a selectable frequency and voltage by utilizing the PWM technology. The 1336VT-B025-EAP-FA2-L2 drive has either a voltage of 380V AC, 415V AC, or 460V AC, with a 41A output current, and 27KVA output power at 380V AC, 29KVA at 415V AC, and 33KVA at 460V AC. The drive has a voltage range of 380V AC to 460V AC (3-phase), with ±10% input tolerance at 47 to 63Hz, and its displacement power factor is 0.95.  The 1336VT-B025-EAP-FA2-L2 has an input current of 35A, with an input power of 23KVA, 25.2KVA, and 27.9KVA at 380V AC, 415V AC, and 460V AC, respectively. It provides AC over and under-voltage trips of up to 570V AC and 275V AC, and it provides Line Transient Protection of up to 5000V.

The 1336VT-B025-EAP-FA2-L2 drive has a logic ride thru time of 2s, and it provides motor control by using the programmable Volt per Hertz control with a 1 to 14.3V/Hz minimum control range, and it provides output control using Sine-Coded Pulse Width Modulated Signals, with an output frequency range of 0 to 250Hz corresponding to A 0 to 380V AC, 415V AC, or 460V AC output voltage range.  The drive offers 2 programmable and independent acceleration and deceleration times programmable between 0 and 600 seconds, with 0.1-second increments, and the drive can provide NEC and UL-rated Motor Overload Protection. The 1336VT-B025-EAP-FA2-L2 has a basic control panel option, with both display and programming panels, used for viewing drive operations/modes, and for programming drive’s parameters, and it also has a logic interface board option (L2) which helps prevent errors in operational loops. The drive’s operating temperature range is 0 to 40°C, at 5 to 95% non-condensing humidity, and its storage temperature range is – 40 to 85°C. It is meant to be installed at a maximum altitude of 3,300ft without de-rating, and it can withstand a 1G vibration and a 15G shock for a duration of 15ms. The 1336VT-B025-EAP-FA2-L2 weighs approximately 16.5KG in a NEMA Type 1 enclosure, and it has shipping volumes of 283mm x 477mm x 223mm.
