Convo Inverter Cvf-s1 Manual |work| May 2026
The Convo CVF-S1 is a compact, low-power single-phase variable frequency drive (VFD) designed for general industrial applications. Now under the Bosch Rexroth umbrella after their acquisition of Convo Electric, the S1 series is typically utilized for controlling three-phase AC induction motors in environments like fans, pumps, and small machinery. Key Technical Specifications
Functional Features
- Automatic Voltage Regulation (AVR): Stabilizes output during input voltage fluctuations to reduce battery usage.
- Smart Charging: Multi-stage charging (bulk, absorption, float) to prolong battery life; charging current adaptable to battery type.
- Eco/UPS Mode: Eco mode prioritizes inverter efficiency (switches to mains when available); UPS mode ensures continuous pure sine output.
- Cold Start: Allows inverter to start from battery without mains.
- Bypass/Generator Compatible: Supports direct mains bypass; safe to use with standby generators.
- LCD/PC Software Monitoring (on some models): Real-time status, event logs, configurable settings via USB/RS232 or Bluetooth.
- Parallel Support (select models): Ability to parallel multiple units for higher capacity.
- Maintenance Alerts: Low-battery and battery replacement notifications.
- User Controls: Mode selection (UPS/Eco/Charge), replaceable fuses, battery isolation switch on some models.
