PS1112S Power Supply for Stable 12 V Output
The PS1112S Power Supply is designed to provide a reliable and extremely low noise 12 V power source for sensitive laboratory instruments and measurement devices. Precision electronic equipment often requires a clean power supply in order to maintain accurate readings and stable operation. Traditional switching power supplies can introduce electrical noise that may affect measurement results. The PS1112S Power Supply solves this problem by delivering a stable output with very low ripple and noise levels.
With a maximum output power of 14 W and a rated current of up to 1.2 A, this power supply is well suited for powering precision electronics such as electrometers, picoammeters and other sensitive instrumentation. The design ensures that the connected devices receive a clean and stable power source that helps maintain high accuracy during operation.
Low Noise Hybrid Design
The PS1112S Power Supply uses a carefully engineered mixed switching linear design that combines the efficiency of switching regulation with the low noise characteristics of linear regulation. This hybrid architecture allows the power supply to achieve an optimal balance between electrical performance and energy efficiency.
The switching stage provides efficient power conversion while the linear regulation stage filters the output to minimize ripple and electrical interference. As a result, the unit achieves a total noise and ripple level of approximately 0.003 percent RMS and 0.025 percent peak to peak across the DC to 1 MHz frequency range.
This extremely low noise performance makes the PS1112S Power Supply particularly suitable for applications where measurement precision is critical and even small disturbances in the power supply could affect results.
Power Supply for Reliable Laboratory Integration
The PS1112S Power Supply is built inside a compact and durable stainless steel enclosure that provides excellent mechanical protection and long term reliability. The compact design allows the power supply to be placed close to the connected instrument, reducing cable length and minimizing the risk of external noise pickup.
This power supply is widely used with advanced measurement instruments such as multi channel electrometers and picoammeters. By providing a stable and noise free power source, the PS1112S Power Supply helps ensure that measurement devices can operate at their highest possible accuracy.
With its compact construction, high efficiency hybrid design and extremely low noise output, the PS1112S Power Supply offers a dependable solution for powering sensitive instrumentation in research laboratories and precision testing environments.
