Common questions about the UltraHeat SM Series induction heating power supplies, including the SM-2/200, SMT-2/200, and SHT-2/400 models.
Can I use an External Control Panel with the UltraHeat SM Series?
Yes. UltraFlex offers optional External/Remote Control Panels for all SM Series models, allowing you to operate the system from a distance. This is useful in automated production lines or when the power supply is mounted inside a cabinet. The panel provides full access to power control, program selection, and system status.
What type of thermocouple does the SM Series use?
The SMT and SHT models support optional temperature monitoring using a Type K thermocouple, which covers a measurement range from −200°C to 1,260°C. This enables closed-loop temperature control for repeatable heating processes. An IR sensor input is also available as an alternative temperature measurement method.
Is there a serial interface option for system integration?
Yes. The SMT and SHT models offer an optional RS-485 serial interface for integration with PLCs, SCADA systems, and other automation controllers. This enables remote monitoring, data logging, and process diagnostics from a central control system. The base SM-2/200 model does not include this option.
Which heat stations are compatible with this power supply?
The UltraHeat SM Series is compatible with the HS-4AN, HS-4W, and HS-5W heat stations. Your choice of heat station depends on the application — coil size, part geometry, and required heating pattern. Both water-cooled and air-cooled configurations are supported. Our application engineers can recommend the best combination for your process.
Can I use 0–10V or 4–20mA for external power control?
Yes. The SM Series supports both 0–10V analog and 4–20mA current loop inputs for external power control via the optional Digital I/O Interface board. These are standard industrial signal types, making integration with existing PLCs and process controllers straightforward. On the SMT and SHT models, Digital I/O comes standard.
What is the frequency range of the UltraHeat SM Series?
The SM-2/200 and SMT-2/200 operate at 30–200 kHz, while the SHT-2/400 covers 100–400 kHz. All models deliver full rated power across their entire frequency range. The system automatically tunes to the optimal frequency based on the coil and workpiece combination, eliminating manual adjustment.
How many user programs does the SM Series support?
The base SM-2/200 supports 5 user programs, while the SMT and SHT models offer 10 user programs with multiple programmable parameters each. Programs store complete heating profiles — power level, time, temperature limits — making changeover between different applications quick and repeatable.
What are the cooling water requirements?
The SM Series heat stations require a minimum water flow of 2 L/min (0.5 GPM) with inlet pressure between 3 bar (45 PSI) and 6 bar (90 PSI). We recommend using deionized or distilled water to protect internal components and extend system life. See our water quality recommendations for more details.
