MEAN WELL Industrial Power & Reliability Portfolio
SPV Series (Programmable Power) & ERDN Series (Redundancy Modules) | 150W~300W | 20A~40A
Advanced Power Delivery & System Security
This specialized portfolio combines the highly adaptable SPV Series enclosed power supplies with the bulletproof reliability of the ERDN Series redundancy modules. Together, they provide a complete solution for systems requiring precise voltage control and guaranteed uptime.
Core Series Advantages
- SPV Series (150W / 300W): Features built-in active PFC and an exceptionally wide Programmable Voltage (PV) range, allowing users to scale the output voltage from 20% to 110% using an external control signal.
- ERDN Series (20A / 40A): Enclosed-type redundancy modules that ensure continuous operation. They support 1+1 and N+1 redundancy setups with an ultra-low voltage drop (0.2V max) to maximize overall system efficiency.
- Industrial Grade: Both series are built for harsh industrial environments, featuring comprehensive electrical protections and high-reliability components.
SPV-150 & SPV-300: Programmable Power Supplies
The SPV series stands out with its ability to dynamically adjust the output voltage, making it ideal for burn-in facilities, laser equipment, and automated testing environments.
| Model Series | SPV-150 | SPV-300 |
|---|---|---|
| Max Rated Power | 150W | 300W |
| DC Voltages Available | 12V, 24V, 48V | 12V, 24V, 48V |
| Input Voltage Range | 88 ~ 264VAC / 124 ~ 370VDC | 88 ~ 264VAC / 124 ~ 370VDC |
| Max Efficiency (Typ.) | Up to 83% | Up to 86.5% |
| Cooling Method | Free Air Convection | Built-in DC Fan (with speed control) |
| PFC Function | Built-in (PF > 0.94) | Built-in (PF > 0.95) |
ERDN20 & ERDN40: Redundancy Modules
The ERDN series protects critical systems by allowing two power supplies to be connected in parallel. If one fails, the ERDN module instantly seamlessly routes power from the secondary unit without interruption.
| Model Series | ERDN20 | ERDN40 |
|---|---|---|
| Max Output Current | 20A (Continuous) | 40A (Continuous) |
| Input Channels | 2 Channels (0~20A each) | 2 Channels (0~40A each) |
| Voltage Options | 5V, 12V, 24V, 48V | 12V, 24V, 48V |
| Voltage Drop (Max) | 0.2V | 0.2V |
| Efficiency (Typ.) | Up to 98% | Up to 98% |
| Reverse Current (Max) | 1mA | 1mA |
Smart Control & System Diagnostics
SPV Series: Programmable Voltage (PV) & Control
- 20~110% Voltage Adjustment: The output voltage can be dynamically trimmed from 20% to 110% of the rated value by applying an external 1 ~ 5.5VDC control signal.
- Remote ON/OFF: Easily toggle the power supply output using the remote control circuit (Power ON: 4~10VDC; Power OFF: <0~0.8VDC or Short).
ERDN Series: Dual Input Alarms
- Relay Contact Alarm: Built-in 30VDC/1A relay contacts trigger an alarm if either of the two input voltages drops below a specific safe threshold.
- LED Status Indicators: Green "OK" LEDs visually confirm the status of the inputs.
- Threshold Examples: On a 24V system, the alarm triggers if the input falls below 18V or spikes above 31V. On a 48V system, it triggers below 34.2V or above 63V.
