K8AKPM2

Overview of Omron K8AKPM2

The Omron K8AKPM2 is a phase monitoring relay designed for three-phase power supply systems, supporting both 3-wire and 4-wire configurations at voltages ranging from 220 to 480 VAC. It monitors overvoltage, undervoltage, phase loss, and phase sequence to ensure the safe operation of equipment relying on three-phase power.

Key Features

• Monitors overvoltage and undervoltage with adjustable setpoints from -30% to +25% of rated voltage.
• Detects phase loss and phase sequence errors to prevent equipment damage.
• Two SPDT relay outputs rated 5 A at 250 VAC resistive load, allowing separate indication and control.
• Low power consumption, approx. 4.4 VA.
• Mounting: DIN rail mountable with space-saving 22.5 mm width.
• Adjustable power-on lock time (1 s or 5 s) and operating time settings from 0.1 to 30 seconds.
• Operating ambient temperature range: -20°C to 60°C.
• High mechanical durability with 10 million operations minimum and electrical durability of 50,000 operations at rated load.
• Conforms to international safety standards (UL, CSA, CE, CCC).
• LED indicators for Power (Green), Relay (Yellow), and Over/Under voltage status (Red).

Technical Specifications

Applications

The K8AKPM2 is widely used in industrial electrical panels and control systems to monitor three-phase supply health, protecting motors, transformers, and other critical equipment from voltage and phase abnormalities. Its precise monitoring and robust relay outputs enhance system reliability and safety.
