Frequency Inverter Model AHD12 Key features and specifications Model: AHD12 Size: DC400600V_3 PHASE 380VAC Color: 2.2kw Input voltage: 3 phase 380V AC Output voltage: 3 phase 380V AC Output frequency range: 0999 Hz Output type: triple (3phase) Output power range: 1 200 KW Power options: 0.75 KW to 2.2 KW Input frequency: 50/60 Hz Operating temperature: 10 to 65 C Weight: 1.5 kgs What this inverter does and why it helps Provides precise speed and torque control for 3phase motors by converting DC to adjustable AC output up to 999 Hz. Improves conversion efficiency for motordriven equipment, enabling smoother start and stop, reduced mechanical stress, and better process control. Supports a wide range of motor sizes and applications with an overall output power capability of 1 to 200 KW and specific unit power options from 0.75 to 2.2 KW. Design and installation notes The inverter wiring is separated into a main circuit and a control circuit for clear layout and service access. A removable cover over the terminals reveals both main circuit and control circuit connections. Follow the provided wiring diagram and connect terminals correctly before poweron. Compatible with standard 3phase 380 V AC systems and designed to work with a DC link voltage in the DC 400 to 600 V range. Performance and reliability Wide frequency span up to 999 Hz allows finegrained speed control for demanding applications. Stable operation over a broad temperature range from 10 to 65 C supports varied installation environments. Compact and lightweight at 1.5 kgs for easier mounting and integration into control panels. Common applications Pump and blower control: adjust motor speed to match flow requirements, reduce energy waste, and minimize water hammer or pressure spikes. Conveyor and material handling: provide smooth acceleration and deceleration, better process synchronization, and reduced mechanical wear. Machine tools and small automation equipment: precise spindle or feed rate control, enabling improved cut quality and consistent cycle times. Additional notes Verify compatibility with your motor specifications and control requirements before installation. Always follow the supplied wiring diagram and local electrical codes when connecting main and control circuits.
