Advanced capabilities

Detailed network functions stay available here without interrupting the main selection path.

Output timing

At full load, start time is ≤3 seconds with 120V AC input and ≤2 seconds with 220V AC. Hold time is ≥10ms at 120V AC and ≥20ms at 220V AC. Voltage overshoot is <5%.

Connection and cooling

Fanless cooling. The mechanical drawing specifies a center-positive 5.5 × 2.1mm DC plug and approximately 1.5m output lead. Match the voltage, plug and polarity to the powered equipment.

Environmental limits

Operating humidity: 20–90%, non-condensing. Storage: −40°C to +85°C and 5–95% RH, non-condensing.

Isolation and EMC

The datasheet lists 100MΩ insulation resistance and input-to-output dielectric testing at 3kV AC. EMC references include EN 55022 Class A and IEC 61000-3-2 Class A.
