Product Introduction
The TRACO POWER TIS600-148-SIG is a high-capacity industrial switching power supply designed to provide regulated 48VDC power for automation cabinets, process-control equipment, and industrial DC distribution systems. Its 576W output capacity and 12A current rating make it suitable for applications with substantial DC power requirements. The output can be adjusted within the documented 48–52VDC range to accommodate specified system requirements.
TIS600-148-SIG
The distinguishing feature of the TIS600-148-SIG is its integrated signal-monitoring functionality. Unlike a basic TIS600-148 supply, the SIG version provides relay contacts for AC input failure and DC output power-good status, together with remote ON/OFF control. These functions allow the power supply to communicate its operating condition to a PLC, DCS, or external alarm circuit.
Major Features and Advantages
High-capacity 48VDC output
The 12A output rating provides up to 576W of DC power for industrial equipment requiring a 48V distribution rail. Output adjustment allows limited voltage trimming within the specified range.
AC power-failure monitoring
The SIG option includes a relay contact for detecting loss or reduction of the AC input supply. This signal can be incorporated into an external alarm or supervisory circuit.
DC power-good indication
A separate relay monitors output voltage and provides a status contact when the DC output exceeds the specified threshold. For the 48V model, the documented switching threshold is approximately 45.6VDC.
Rx Electronics
Remote ON/OFF control
The power supply supports remote control through a dedicated signal connection. The documented control arrangement uses a short circuit between the specified connector pins for ON and an open circuit for OFF.
Industrial protection functions
The TIS 600 series includes overload, short-circuit, and overtemperature protection. These functions help protect the supply and connected equipment under abnormal operating conditions.
Application Scenarios and Field Pitfalls
Typical applications include:
- 48VDC industrial control cabinets.
- DCS and PLC auxiliary power distribution.
- Industrial communication and instrumentation equipment.
- Redundant DC power architectures.
- Process-control systems requiring external power-failure alarms.
Important installation checks:
- Confirm the AC input selection and supply voltage before energizing.
- Verify the DC load does not exceed 12A or 576W.
- Check output voltage adjustment before connecting sensitive equipment.
- Verify the AC-failure and power-good relay terminal assignments.
- Confirm the remote ON/OFF wiring logic.
- Maintain sufficient ventilation around the metal enclosure.
- Apply the manufacturer’s temperature derating requirements above the specified ambient range.
Field warning: Do not confuse TIS600-148-SIG with TIS600-148 or -RED. The SIG suffix identifies additional monitoring and control functions. A standard version may provide the same nominal output voltage and current but lack the required signal interfaces.
Related Products and Variants
| Model | Main Configuration |
|---|---|
| TIS600-124 | 24VDC, 24A power supply |
| TIS600-124-SIG | 24VDC version with signal functions |
| TIS600-124-SIG | 48VDC, 12A standard version |
| TIS600–SIG | 48VDC, 12A version with signal functions |
| TIS600–RED | 48VDC redundancy-oriented version |
| TIS600-172 | 72VDC output version |
These models share the TIS 600 product family but differ in output voltage or functional configuration.
Procurement and Quality Control
For a TRACO POWER -SIG replacement, request:
- Complete model and nameplate photographs.
- AC input operation test results.
- 48VDC output voltage measurement.
- Full-load output-current test up to the specified rating.
- Ripple and noise measurement.
- AC power-failure relay test.
- DC power-good relay test.
- Remote ON/OFF functional test.
- Inspection of DIN-rail mounting clips and terminal blocks.
- Confirmation of new, used, or refurbished condition.
Engineering recommThe should be selected when both 48VDC power delivery and external power-status signaling are required. During replacement, verify the three SIG control functions independently; matching the 48V and 12A ratings alone does not establish functional equivalence.
