Technical Information

Insulation and Dielectric Strength

• Insulation Resistance: Rated at 100 MΩ at 500 VDC between all input and output terminals, ensuring robust insulation.
• Dielectric Strength: Tested at 3,000 VAC for 1 minute between input and output terminals, and 1,500 VAC between input terminals and the frame ground.

Environmental Tolerances

• Operating Temperature: -10 to 50 °C
• Storage Temperature: -25 to 65 °C
• Humidity: 25 to 85% RH (operating), 25 to 90% RH (storage)

Installation Options

• Mounting: The SPB series supports both DIN rail clipping and screw mounting, allowing flexible installation options.

Ordering Information

When selecting a model from the SPB series, consider the following identifiers:

• Output Power: The model number reflects the output power in watts (W).
• Output Voltage: The model number also indicates the output voltage in volts DC (VDC).

For example, SPB-015-12 corresponds to a 15W power supply with a 12V DC output.
