Supported Applications
The Dwyer Model SCD-PS is a DIN Rail Mount DC Power Supply designed to provide power for pressure, humidity, temperature, level, or air velocity transmitters. It functions as an open-type unit intended for installation within an enclosure to protect against dust, humidity, electric shock, and vibration.
Operating Conditions & Performance
The SCD-PS accepts a universal AC input of 100–240 VAC (-15%~+10%), 50 / 60 Hz. It delivers a regulated DC output of 24VDC (±3%) with a maximum current capacity of 1A. The unit features auto-recovery protection for over-load and short circuit conditions, maintaining operation during power cuts shorter than 10ms.
Performance specifications include:
- Ripple & Noise: Under 100mVp-p typical at full load
- Efficiency: 78%~87% typical at full load
- Ambient Temperature (Operation): 32 to 131°F (0 to 55°C)
- Humidity (Operation): 50~95%
- Storage Environment: -25°C ~ 70°C, 5~95% humidity
The unit weighs 158 g (5.6 oz) and requires a minimum clearance of 50mm on all sides for heat dissipation.
Configuration Options
The SCD-PS series is configured as a DIN rail mount device with fixed terminals labeled L, N, +24V, and 0V. A plastic cover slides over the terminals to prevent accidental contact with high voltage wires. The unit includes a green 'POWER' LED indicator on the front panel.
Key configuration details include:
- Housing Style: Open-type design requiring an external enclosure
- Mounting: DIN rail mount with terminal block access
- Grounding Requirement: Ground wire diameter must not be smaller than the L and N terminals; use wires of 1.6mm or larger for grounding.
- Pollution Degree: Pollution degree 2 (Operation)
Key Product Differences
The series is identified by the model number SCD-PS, described as a "DIN rail DC power supply." The unit complies with Underwriters Laboratories, Inc.: UL508 Listed (Industrial Control Equipment) and carries CE and cULus approvals. It meets European Community EMC Directive 89/336/EEC and Low Voltage Directive 73/23/EEC requirements.
Installation notes specify that AC input must be connected to terminals L and N; connecting AC voltage directly to the +24V terminal will permanently damage the unit. The device is not suitable for dusty, smoky, or corrosive atmospheres without appropriate enclosure protection.
