Overview
The SL 1 Series Frequency Converter is a cost-effective solution designed for speed control of small three-phase motors in commercial and light industrial applications. Engineered with a compact design and essential control features, this converter balances performance, affordability, and ease of use, ideal for pumps, fans, and conveyors in small-scale systems.
Features
Economical Performance:
Power range: 0.1-3.7kW, supporting single-phase input (220V) to three-phase output, suitable for retrofitting single-phase systems to three-phase motors.
V/f control mode with slip compensation, ensuring stable speed regulation (±1% under full load) at an affordable price point.
Space-Saving Design:
Ultra-compact size (70x120x100mm for 0.75kW), fitting into standard electrical boxes and saving 50% space compared to traditional drives.
DIN rail mounting with snap-lock mechanism, enabling tool-free installation in 5 minutes.
Reliability & Simplicity:
IP20-rated enclosure with built-in braking resistor (100W), providing quick stop capability (≤2 seconds for 0.75kW motor).
Basic protection: overcurrent (1.5x rated), overheat (80°C), and phase loss detection, compliant with IEC 60204-1 machine safety standards.
User-Friendly Operation:
4-digit LED display for parameter setting (50+ adjustable parameters), with quick-start guide reducing commissioning time to 10 minutes.
Analog input (0-10V/4-20mA) for speed control, with optional potentiometer for local speed adjustment.
Application
Suited for small-scale applications, the SL 1 Series is used in:
Commercial HVAC: Controls fan coils and condensate pumps in offices and retail stores, reducing noise and energy use by 20%.
Food Processing: Regulates conveyor speed in packaging lines, with stainless steel variants (IP65) for washdown environments (e.g., bakeries, dairies).
Woodworking Shops: Drives spindle motors in table saws and routers, supporting variable speed cutting (0-3000 RPM) for different materials.
Water Supply Systems: Adjusts pump speed in residential water towers, maintaining constant pressure (±0.1 bar) with PID control.
