Considérations clés en matière de sélection (5 Dimensions)

1. Power Demand Matching

Standard load (≤11A): Choose 140CPS11420 standalone mode

Redundancy required (≤20A): Two 140CPS11420 in parallel for higher system reliability

High load (>20UN): Select 140CPS21420 (20A single module) or multiple modules in parallel

2. Power Supply Environment Adaptation

115V/230V AC grid: 140CPS11420 (entrée large, no manual switching needed)

DC power supply scenario: Choose 140CPS31420 (24VDC input)

Extreme temperature: Select wide-temperature version for -25°C~+70°C

3. Redundancy Strategy Design

Non-redundant: Single 140CPS11420 standalone

Basic redundancy: Two 140CPS11420 parallel (total 20A)

Full redundancy: Three 140CPS11420 (2 active + 1 standby) for maximum availability

4. Alarm Function Requirement

Standard alarm: Built-in NC relay contact (6A@220V AC) on 140CPS11420

Surveillance à distance: Add 140NOE77100 Ethernet module for network-based power status monitoring

5. Installation Space Evaluation

10-slot rack: Max. 2 power modules installed (1 recommended for redundancy reserve)

16-slot rack: Max. 3 power modules (2 active + 1 standby)

Space limited: Choose 140CPS21420 (20A single module)
