Traco Power Switching Regulator, SIP-5 Format, 93% Efficiency - TSR 3 Series - TSR 3-1250

Change up your power supply to suit your equipment with this switching regulator from Traco Power. It's a versatile option that takes an input voltage between 4.5 and 14V DC and turns it into a steady output between 0.6 and 6V DC. By converting 93% of its load, the component minimises energy wasted as heat, so you can skip the hassle of hooking up a heatsink. Tucking it onto a busy PCB is no issue, thanks to its compact SIP-5 format. As it's protected against short circuits, this converter steers clear of damage caused by electrical faults.

Features & Benefits

• Through-hole mounting style means it slots into pre-drilled board holes for convenient set-up
• Low ripple voltage of 50mV to minimise disruptive electrical noise
• Open-frame design promotes airflow for effective passive ventilation
• Load regulation of 0.8%, so you get stable power supply through input changes

Applications

• Consumer electronics
• Server management
• Automotive engineering

What's the benefit of the device's remote on/off function?

By controlling your hardware with a remote on/off circuit, you can easily power an appliance up and down from a central panel without having to manually switch it.
