Category Parameter Specification / Typical Value Function & Compatibility Function DC OK / Power Good Signal Compatible Series Eaton P1 Series and P3 Series Power Supplies Mounting Snap-on or direct attachment to the compatible power supply unit Signal Contact Characteristics Contact Type Floating Changeover Contact (SPDT) - 1 NO (Normally Open) + 1 NC (Normally Closed) Contact Rating (Max.) Typically 240V AC, 2A or 30V DC, 2A (Resistive load) Operation State Relay is energized when DC output voltage is normal. Electrical Characteristics Supply Voltage Self-powered from the host power supply (no external wiring required) Response Time Typically a few tens to hundreds of milliseconds (to avoid nuisance tripping on short dips) General Data Connection Type Screw Terminals for the signal contact output Status Indication Usually an LED indicator to show the "DC OK" status Operating Temperature -25 °C to +60 °C (or as per the host PSU specification) Standards Relevant parts of IEC/EN 60947, UL 508
