What is the Starter 1-Phase?
The HPzenAi Starter 1-Phase (SP-1P) is a complete smart motor starter assembly for single-phase 220V AC motors. Unlike the MX-1P retrofit module, the SP-1P includes a single-phase contactor and overload relay built into the assembly — the motor wires directly to the SP-1P output terminals. A built-in MX-1P IoT module provides remote control, scheduling, dry-run protection, and fault monitoring via the HPzenAi app and gateway.
Complete Assembly
Contactor, overload relay, and IoT control module pre-wired and assembled — wire in L, N, and motor output; the unit does the rest
Built-In Overload Protection
Integrated thermal overload relay with adjustable FLA dial — set to motor nameplate current for motor burn-out protection
Remote Start/Stop
Remote manual control, scheduling, and sensor-triggered automation via the HPzenAi app and RS485-connected gateway
Dry-Run Protection
Integrates with HPzenAi LS-PRE level sensors to stop the motor automatically when the water source runs dry
