What AutoLink solves

Standard rotary phase converters use a fixed capacitor bank optimized for a specific load. When the actual load varies significantly — as it does with compressors, HVAC equipment, or shops running multiple machines — voltage balance can degrade. AutoLink monitors the output in real-time and switches capacitors in and out automatically to maintain balance at any load point.

Who needs NLTA?

• Air compressors (460V) — hard-starting, variable duty cycle loads
• HVAC and refrigeration equipment (460V) — constant load variation
• Shops with multiple 460V machines — total load varies as machines cycle on and off
• Dust collectors and industrial ventilation — frequent start/stop
• Grain dryers and agricultural processing at 460V
• Industrial pumps with variable flow demands

How AutoLink Works

The AutoLink system uses a microcontroller to continuously monitor the three-phase output voltages. As load increases or decreases, it switches additional capacitors in parallel or removes them from the circuit — all in milliseconds. The result is consistent voltage balance across a wide load range.

• Real-time monitoring — measures output balance continuously
• Automatic capacitor switching — adjusts to load changes in milliseconds
• Wider operating range — maintains balance from 25% to 100% load
• No user adjustment needed — set and forget

NLTA vs NLT

Choose NLTA over NLT when:

• Your load varies by more than 30% during operation
• You're running hard-starting loads like compressors or HVAC
• You'll eventually add more equipment and want room to grow
• Voltage imbalance under varying loads is a concern
