CHE100-1R5G-S2 Variable Frequency Drive CHE100 1.5kW 1-ф/220

CHE100-1R5G-S2 — single-phase frequency inverter from INVT CHE100 series, rated at 1.5 kW active power capacity (nominal output current 7 A) for electrical grids with 1-phase 220V supply voltage. The VFD supports sensorless vector control (SVC) and scalar V/F control, delivering smooth motor speed adjustments and dynamic torque response. The device features IP protection standard, integrated EMC filter, and built-in Modbus RTU RS-485 communication interface.

Typical Applications:

• Industrial conveyors, mixers, extruders, and packaging machine drive systems.
• HVAC fans and automated pump systems utilizing built-in PID controller for constant pressure hold.

Please Note: Perform motor autotuning (rotating or static) before first system startup. When installing motor cables longer than 50 meters, an output reactor (du/dt filter) is highly recommended to protect motor winding isolation from voltage spikes.

INVT CHE100 — Positioning

The INVT CHE100 frequency inverter series represents a classic legacy lineup of compact, single-board drives designed for simplified industrial automation and speed control tasks. Despite its legacy status, the drive remains a highly reliable solution powered by a DSP control system that delivers quality scalar V/F control and basic Sensorless Vector Control (SVC). The single-board layout makes the physical construction robust and highly service-friendly, while the built-in braking unit across the entire range (0.4 to 11 kW) eliminates the need for expensive external dynamic braking modules.

Key Industrial Applications for INVT CHE100

• Local Water Booster and Irrigation Pumps: Driving centrifugal pumps with the integrated PID controller and multi-point U/F curves to lower starting current draw and optimize pipeline pressure.
• Low-Capacity Conveyors and Belts: Providing smooth acceleration and deceleration of transport bands while maintaining high starting torque (up to 150% at 0.5 Hz in Sensorless Vector mode).
• Auxiliary Machine Tooling spindles: Cost-effective speed control of spindles in woodworking, packaging, or textile machinery via standard digital and analog interfaces.

What Differentiates INVT CHE100 from Competitors

Unlike Delta VFD-L, the CHE100 series supports direct connection of braking resistors to the power terminals and provides basic vector capabilities to handle dynamic torque fluctuations.

When INVT CHE100 is NOT Suitable

• This legacy series is not designed to control modern energy-saving Permanent Magnet Synchronous Motors (PMSM) or high-precision servo systems. For these modern tasks, we recommend choosing the current vector series INVT Goodrive20 or the advanced INVT GD350 drives.

Our Practical Experience with INVT CHE100

Years of CHE100 operation across small workshops in Ukraine prove its exceptional resilience and minimal maintenance requirements. Experienced engineers appreciate CHE100 for its simplified Modbus RTU register mapping (start/stop control is mapped to 2000H, and frequency reference is written to 3000H), facilitating quick integration into entry-level PLC and SCADA automation architectures.
