Summary of DOWNSIZE YOUR BENCH POWER SUPPLY WITH THE R4K-36 SERIES
The R4K-36 by Matsusada Precision is a palm-sized variable DC lab power supply offering typical bench features in a very compact form. It supports three memorized settings, output delay, two lock modes, current sink and sink-prevention, series connection up to 16 units, dual tracking, digital interfaces, remote on-off and sensing, and optional pulse/ramp sequencing with master follow—making it suitable for productive home labs where space is limited.
Parts used in the R4K-36 Project:
- R4K-36 palm-sized variable DC power supply (Matsusada Precision)
- Front-panel controls (knobs/buttons for voltage and current)
- Memory setting function (stores 3 voltage/current presets)
- Delay trigger circuitry (0.0 to 99.9 seconds)
- Locking mode mechanism (two lock modes)
- Current sink and sink prevention circuitry
- Series connection terminals (to connect up to 16 PSUs)
- Dual tracking output configuration
- Digital interface ports (for communication)
- Remote on-off control and remote sensing connections
- Optional pulse and ramp sequence module with master follow function
In a time where we spend all our time at home, we start looking for ways to enhance our productivity. You may believe that nothing will ever beat your lab at work or college, and let me tell you, you are dead wrong! Today we will take a look at a very convenient palm-sized variable DC power supply, which has the potential to make your work at home more enjoyable!
The R4K-36 product, developed by Matsusada Precision, is a lab bench power supply series with the features you expect from one, but with a simple characteristic that makes a world of difference: it is incredibly compact. If you recall, these power supplies usually take up more space than almost any other appliance in the lab, and with this one, the space problem simply goes away, you can just tuck it anywhere and it will blend with the environment.
But of course, a power supply is not just made of its size, so what is there that may deserve my attention (and money)? We will see:
- Multi setting function, to memorize 3 different voltage and current settings
- Delay trigger function, to delay the output in a range of 0.0 to 99.9 seconds
- Two different locking modes, to avoid mis-operation and those accidental knob-bumbs
- Sink current + sink current prevention function
- Connection of up to 16 PSU’s in series (if you have them, you probably just need 2, one for positive and the other for negative rails)
- Dual tracking, with multiple outputs
- Digital interfaces available
- Remote on-off control and remote sensing
- Pulse and ramp sequences + master follow function (optional)
