SMITHS Hi‑REG XRC‑1.4 is an industrial high-precision regulated power supply developed by Smiths Heimann of the UK (now part of Smiths Detection). It has a rated capacity of 1000 VA and accepts 120/240 VAC input at 50/60 Hz. Specially designed for X-ray detection, industrial inspection and precision instruments, it features low ripple, high stability and strong anti-interference performance. Though discontinued, it is still widely used for the maintenance of existing equipment.
Product Advantages
Ultimate voltage regulation accuracyAdopting HI-REG patented voltage regulation technology, the output deviation is less than ±0.1% despite load and input voltage fluctuations, ensuring stable operation of precision loads such as X-ray tubes.
Ultra-low ripple and noiseOutput ripple is below 5 mV, ideal for scenarios demanding extremely high power purity including spectral analysis and non-destructive testing.
Wide input compatibilityAuto-adaptive to 120/240 VAC and compatible with 50/60 Hz worldwide, supporting both industrial power grids and generator power supply.
Industrial-grade reliabilityEquipped with an all-metal shielding enclosure for dust resistance and anti-interference. Designed for an operating temperature range of 0–40°C, it delivers long-term stable performance in harsh industrial environments.
Integrated protection functionsFour-fold protection against overvoltage, overcurrent, short circuit and overheating. It locks automatically upon faults to prevent load damage.

Frequently Asked Questions
Q: Why has the XRC‑1.4 been discontinued? Are there any replacement models?A: It was discontinued due to component updates and product line upgrades. The officially recommended replacement is XRC‑10.0, an upgraded model of the same series with 280 VA power and fully compatible parameters. Domestic high-precision power supplies dedicated for X-ray equipment are also available as third-party alternatives.
Q: The fault indicator lights up and there is no output after power-on. How to troubleshoot?A: 1. Verify the input voltage (120 V/240 V) matches the requirement.2. Check for short circuits or overload on the output side.3. Clean the fan dust and confirm no overheating protection is triggered.4. Power off and restart the device. If the fault persists, internal circuit maintenance is required.
Q: What causes large output voltage fluctuation and excessive ripple?A: 1. Unstable input voltage: Install a voltage stabilizer.2. Overlong load wiring or poor contact: Shorten cables and fasten terminals securely.3. Dust accumulation causing poor heat dissipation: Clean the fan and chassis.4. Aged internal capacitors: Replace the capacitors.
Q: Can it be used for non-X-ray precision loads?A: Yes, as long as the load voltage and current stay within the rated output range. Note that this power supply is specially designed for X-ray equipment, so it is not cost-effective for general precision loads.
Q: How to use the remote control interface?A: The device is equipped with standard RS‑232/485 interfaces. Connect it to the host computer via a dedicated data cable and install the supporting software to realize remote voltage/current adjustment, status monitoring and fault alarm. Refer to the official communication protocol manual for detailed operations.
