WSN 0.9 - 230/24 Wide range switching power supply for AC- and DC- mains

Product catalog summary

Overview: The document is a datasheet for the WSN 0.9/24 wide-range switching power supply, designed for both AC and DC mains. It highlights key features, technical specifications, and safety standards.

Key Features:

Switch-on current surge limitation with regulated output voltage.
LED function indication.
Protection against overload, overvoltage, idle running, sustained short circuit, and over temperature with automatic reclosure.
Compact design for DIN-rail assembly, suitable for MFW-products with optional connection cable.

Technical Specifications:

Input Voltage Range: 100-240 V AC (-15%/+10%), 47-440 Hz; 110-220 V DC (-10%/+65%).
Output Voltage: 24 V DC (+2%/-3%).
Rated Output Current: 0.9 A.
Operating Temperature: -10°C to +60°C; 20-90% relative humidity.
Storage Temperature: -20°C to +85°C; 10-95% relative humidity.
Insulation Strength: 3 kV AC between input and output.
Efficiency: Approximately 78%.
Performance Restrictions: Efficiency decreases over 45°C and at lower DC voltages.

Safety and Standards:

Complies with EN60950 and UL1950 safety standards.
EMC Standards: EN50011 (Class B), EN50022 (Class B).

Physical Characteristics:

Pluggable terminals with crosswire section options.
Plastic flame retardant housing with IP 40 protection class.
Weight: 150 g.

Additional Information: The WSN is equipped with a quick electronic overload fuse, making it unsuitable for consumers with high switch-on currents, as this can trigger the fuse and cause periodic start-up tests.
