The challenges of the irrigation season in New Zealand
Maintaining consistent irrigation throughout the season is critical, but even minor breakdowns can quickly escalate into major disruptions for your customers. When a pump fails or equipment falters, delays in sourcing replacement parts or the lack of immediate local expertise can leave systems offline for extended periods, risking your customers' crop health and yield.
With irrigation systems under constant strain from fluctuating demands and unpredictable conditions, quick access to reliable parts and knowledgeable support is vital to avoid costly downtime. The challenge intensifies when high-quality, energy-efficient equipment isn’t readily available, leaving electrical contractors and growers struggling to meet the season’s increased demands.
At Power Electronics, we understand these pain points. That’s why we offer fast, reliable access to tools, replacement parts, and expert local support so that minor issues don’t become major problems.

What we offer
The SD750: Precision and efficiency for irrigation
Our SD750 VSD is designed to meet the unique challenges of irrigation. With advanced Pump Macro features, the SD750 eliminates the need for external control hardware like PLCs, streamlining irrigation systems for electrical contractors and their clients.
Key irrigation features
The SD750 offers a range of irrigation-specific functionalities.
- Pipe fill mode - gently fills empty pipes to prevent pressure surges.
- Pressure setpoint ramp - gradually increases pressure, avoiding overshoot for smooth water delivery.
- Multi-pump control - manages up to five fixed-speed pumps to meet demand efficiently.
- Automatic sleep mode - shuts down during low demand to save energy and reduce wear.
Advanced protection and control
The SD750 protects irrigation systems with features like low water detection, high pressure trip, and cavitation prevention, extending equipment life and minimising downtime. Its built-in dv/dt filter reduces stress on submersible pumps, helping them last longer in tough conditions.
Flexible pump management
With simultaneous triple PID control, the SD750 provides precise management of pressure, flow, and levels, for efficient operation. It supports both lead pumps for large flows and jockey pumps to maintain pressure during low demand, while coordinating multi-master systems for seamless pump operation and redundancy.
Built for reliability
The configurable, automatic fault reset feature, ensures the SD750 can quickly recover from faults, minimising interruptions during critical irrigation periods.
