Review THORLABS Five Photodiodes Visible Wavelengths Power Supply

The Thorlabs CPS186 Constant Power Supply is a versatile and reliable solution for driving photodiodes and other low-voltage, current-controlled devices in the visible wavelength range. This power supply is designed to provide a stable and accurate output, making it an excellent choice for applications in research laboratories, industrial settings, or OEM systems.

The CPS186 is a DC power supply that can deliver a continuously adjustable output current from 0 to 20 mA and a voltage range from 0 to 1.5 V. This wide current range allows it to be used with various types of photodiodes, including silicon, germanium, and InGaAs photodiodes, among others. The supply also features a built-in current limiting function, ensuring that the photodiode is never overdriven, which helps to prevent damage and improve the overall performance of the system.

The user interface of the CPS186 is intuitive and easy to use. It features a large, backlit LCD display that shows the current and voltage settings, as well as the actual output current and voltage. The supply also includes front panel controls for setting the current or voltage manually, as well as a rotary encoder for fine adjustments.

The CPS186 is designed for optimal stability and accuracy, with a low ripple and noise output. It also features a built-in temperature compensation function, which helps to maintain a consistent output current even in changing environmental conditions. The supply also includes an over-temperature protection feature, which shuts off the output if the temperature gets too high, helping to prevent damage to the photodiode or the power supply itself.

The power supply is constructed with high-quality components and is built to last. It features a rugged, anodized aluminum housing that provides excellent thermal management and protects against EMI and RFI interference. The CPS186 also includes a detachable, multi-pin output cable and comes with a comprehensive user manual and software package for easy setup and operation.

Overall, the Thorlabs CPS186 Constant Power Supply is an excellent choice for anyone in need of a reliable and versatile power supply for driving photodiodes or other low-voltage, current-controlled devices in the visible wavelength range. Its wide current range, built-in protection functions, and intuitive user interface make it a favorite among researchers, engineers, and OEM system designers.

The Thorlabs CPS186 Photodiode Power Supply is designed to provide a stable power source for photodiodes used in various applications, including spectroscopy, photometry, and photovoltaics, in the visible wavelength range. Here are some pros and cons of buying this power supply:

1. Wide Voltage Range: The CPS186 can output voltages from 0 to 30 volts, making it suitable for a wide range of photodiodes.

2. High Current Capability: It can deliver up to 1.5 A of current, which is essential for driving high-current photodiodes.

3. Temperature Control: The power supply has an adjustable temperature control feature, which allows users to maintain a stable operating temperature for their photodiodes.

4. Programmable Output: The CPS186 can be programmed to output a specific voltage or current, making it ideal for automated systems.

5. Built-in Protection Circuit: The power supply includes overvoltage, overcurrent, and short-circuit protection, ensuring the safety of the user and the connected equipment.

1. Expensive: Compared to other power supplies in the market, the CPS186 is relatively expensive, which might be a deterrent for some users.

2. Limited Input Voltage: The power supply requires an input voltage of 100-240 V AC, which might not be suitable for all applications or locations.

3. No Built-in Bias Tee: Some users might require a built-in bias tee to apply a reverse bias voltage to their photodiodes, which is not available in the CPS186.

In conclusion, the Thorlabs CPS186 Photodiode Power Supply offers several advantages, including a wide voltage range, high current capability, temperature control, programmable output, and built-in protection circuit. However, its high cost and lack of a built-in bias tee might be disadvantages for some users. Based on its features and performance, I would recommend the CPS186 to users who require a stable and versatile power source for their photodiodes in the visible wavelength range and have the budget for it. For users with limited budgets or specific requirements, such as the need for a built-in bias tee, other power supplies in the market might be more suitable.
