Key Features
- 3 W output power in compact SIP-8 through-hole package for space-efficient designs
- 1600 VDC input-to-output isolation for safe galvanic separation in industrial systems
- 2:1 input voltage range providing flexibility across varying power bus conditions
- Regulated dual ±15 V output supporting precision analog and operational amplifier circuits
Applications
The TMR 3-1223 is ideal for providing isolated 3 W power in industrial fieldbus interfaces, signal conditioning modules, and PLC I/O cards where galvanic isolation up to 1600 VDC is required. Its SIP-8 form factor fits standard PCB through-hole layouts, making it easy to integrate into tight enclosures in process control and automation equipment. The wide 2:1 input range and regulated dual ±15 V output also suit it for powering operational amplifiers and precision sensor front-ends in data acquisition systems.

Frequently Asked Questions
What input voltage range does the TMR 3-1223 accept, and what output voltages does it regulate to?
The TMR 3-1223 accepts a 2:1 input range centered on 12 V, typically 9 V to 18 V, and provides regulated dual ±15 V outputs, delivering up to 3 W of total power. This output is well-suited for op-amp circuits and precision analog signal chains requiring symmetric bipolar rails.
How much isolation voltage does the TMR 3-1223 provide between input and output, and why does that matter in industrial designs?
The TMR 3-1223 offers 1600 VDC galvanic isolation between its input and output, which protects downstream circuits from high-voltage transients and ground loops common in industrial environments. This level of isolation meets requirements in PLC interfaces, fieldbus couplers, and motor drives where safety separation is mandated by IEC standards.
Which package does the TMR 3-1223 use, and how does it mount on a PCB?
The TMR 3-1223 comes in an encapsulated SIP-8 (single in-line package with 8 pins) through-hole format, with a pin pitch of 2.54 mm. It mounts vertically through PCB holes, occupying a small board footprint suitable for dense industrial control cards while providing excellent thermal dissipation through its epoxy-encapsulated body.
When would a designer choose TMR 3-1223 over a non-isolated point-of-load converter in a sensor interface card?
A designer would choose the TMR 3-1223 when the sensor or interface circuit operates at a different ground potential from the control system, such as in 4-20 mA current loop transmitters or RS-485 bus couplers, where 1600 VDC isolation prevents ground current from corrupting the 15 V analog signal rail and protects both the measurement hardware and the user.
