TMR 1211 Datasheet

Traco Power DC-DC Converter, 81% Efficiency, SIP-8 Format - TMR 2 Series - TMR 1211

Seeking a space-saving power and conversion solution? The search is over thanks to this DC-DC converter from Traco Power. It takes any voltage from a broad 2:1 input range of 9 to 18V DC and steps it down to a carefully regulated 5V DC output that's just the thing for your sensitive battery-supplied components. You'll find it's a practical pick when you're short on board space too, as its SIP-8 format is super-compact with a footprint of only 2cm². An 81% efficiency rating means it produces little waste heat and doesn't need a heatsink or fan.

Features & Benefits

• Remote On/Off feature lets you control the device from afar

• Low ripple and noise up to 50mVp-p means minimal disruption from EMI

• Comes with indefinite short-circuit protection to shield you and your kit from common current faults

• Shock and vibration resistance for safe use near moving machinery

• Works reliably across a wide -40°C to +85°C operating temperature range

Applications

• Industrial automation

• Telecommunications networks

• Instrumentation

Does this device protect against surges?

Yes. As it's isolated up to 1.6kV DC, you and your equipment are safe from the harmful effects of rogue electrical spikes.
