Traco Power Switching Regulator, 470μF Maximum Capacitive Load, 92% Efficiency - TSRN 1 Series - TSRN 1-2450A

Pull the plug on erratic power delivery to your PCB-linked devices with this switching regulator from Traco Power. It steps down input signals varying between 6.5 and 42V DC to deliver a stable 5V DC that's safe for low-voltage components such as LED lights. The unit also has an integrated capacitor that cleans out ripple from the supply, giving you noiseless signal transmission. Plastic housing offers impact protection to the workings, as well as effective insulation to shield you from electric shocks during handling.

Features & Benefits

• Conforms to UL 94-V0 standards, meaning it stops burning in 10 seconds or less in the event of a fire
• Mean time between failures of more than 20 million operating cycles assures you of long-term reliability
• Performs optimally in a temperature range between -40°C and +85°C, making it suitable for hazardous locations

Applications

• HVAC systems
• Security and surveillance devices
• Research labs

How do I mount this switching regulator on my PCB?

The unit is designed with pins for vertical through-hole mounting and soldering onto your circuit board. This method achieves a permanent link to your network that resists vibration.
