Delta MH300 18.5 kW (25 HP) Compact Vector Drive (three-phase 460 V)
The Delta MH300 is a high-performance compact vector-control AC drive engineered for demanding industrial duty in a footprint up to 71% smaller than the previous generation. This 18.5 kW (25 HP) model accepts a 3-Phase 380–480 V AC (-15% ~ +10%) supply and delivers a rated 38.0 A output under Heavy Duty (HD) and 41.5 A under Normal Duty (ND), built on a frame F chassis. It supports both induction (IM) and permanent-magnet (IPM/SPM) motors, making it a flexible single platform for a wide range of machines.
Key Features
- Dual motor support — drives induction (IM) and permanent-magnet (PM) motors from one unit.
- High starting torque — up to 200% torque at low speed (0.5 Hz sensorless / 0 Hz with PG feedback) for tough, dynamic loads.
- Built-in PLC (5K steps) for simple standalone logic and distributed control without an external controller.
- Integrated Safe Torque Off (STO) — ISO 13849-1 Cat 3 PL d, EN 61508 SIL 2, removing the need for external safety contactors.
- Built-in brake chopper and Deceleration Energy Control for fast, resistor-free braking on most frames.
- Screwless control terminals and a removable keypad with USB port for fast wiring, programming and offline parameter copy.
Motor Control & Performance
The MH300 offers V/F, sensorless vector (SVC) and field-oriented (FOC) control, with optional PG-feedback closed-loop modes for high-precision speed and torque regulation. Maximum output frequency is 599 Hz, and the drive holds a 1:1000 speed range in FOC+PG mode. Overload capability is 120%/60 s and 150%/3 s in Normal Duty, rising to 150%/60 s and 200%/3 s in Heavy Duty, so this 18.5 kW (25 HP) unit absorbs sudden load impacts without tripping. Deceleration Energy Backup (DEB) lets the motor decelerate safely on a power dip and resume speed when supply returns, protecting the machine.
Communication & Expandability
RS-485 Modbus and CANopen are built in as standard. Two option-card slots add fieldbus connectivity — PROFIBUS DP, DeviceNet, Modbus TCP, EtherNet/IP, EtherCAT or PROFINET — plus PG feedback, analog/digital I/O, relay output or a 24 V external-power card for uninterrupted communication during a mains failure. Tension-control firmware (coil-diameter calculation, dual-PID, taper) is built in for winding and converting machinery.
Reliability & Easy Installation
Every board carries 100% conformal coating to IEC 60721-3-3 class 3C2 for moisture, corrosion and dust resistance, and IP40 variants suit high-dust textile and woodworking environments. The drive supports side-by-side (zero-clearance) installation at -20°C to 40°C, and this frame F unit is fan-cooled with a removable, easy-clean fan module. A built-in Class A (C2) EMC filter is available to save cabinet space and wiring time.
