Wanptek WPS1602H 160V/2A 320W Adjustable DC Power Supply
Wanptek WPS1602H 160V/2A 320W Adjustable DC Power Supply
The Wanptek WPS1602H is a precision laboratory-grade adjustable DC power supply delivering 0-160V output with 0-2A current capability and 320W maximum power rating, designed for demanding electronic testing and development applications. Electronics engineers, circuit designers, and research laboratories rely on this supply for stable voltage and current regulation when prototyping circuits, testing power electronics, and conducting precision measurements. This supply solves the critical problem of providing clean, adjustable DC power with minimal ripple and noise for sensitive analog circuits, digital logic testing, and component characterization.
Product Overview
The Wanptek WPS1602H operates on a linear regulation principle with dual-range voltage selection, allowing users to switch between 0-80V and 0-160V modes for optimal resolution and stability across different load conditions. The power supply features independent voltage and current controls with precise analog meters for real-time monitoring, enabling accurate adjustment to exact specifications. The linear design ensures exceptionally low output noise and ripple, typically below 5mV RMS, making it ideal for powering sensitive analog instrumentation, audio amplifiers, and precision measurement equipment where noise immunity is critical.
This model incorporates comprehensive protection circuitry including over-current limiting, short-circuit protection, and thermal shutdown mechanisms to safeguard both the supply and connected devices. The robust transformer-based design with heavy-duty heat dissipation ensures continuous operation at rated power without thermal throttling. The dual analog meters provide independent voltage and current readouts, allowing simultaneous monitoring of both parameters without switching or menu navigation, which is essential for real-time circuit characterization and fault diagnosis during development work.

How to Use
Begin by connecting the Wanptek WPS1602H to a standard AC 220V, 50Hz wall outlet using the provided power cable. Before applying power to your circuit, set both the voltage and current adjustment knobs to their minimum positions (fully counter-clockwise). Switch on the main power switch and allow the supply to warm up for 2-3 minutes. Select your desired voltage range using the dual-range selector switch: choose 0-80V for loads requiring lower voltages with better resolution, or 0-160V for higher voltage applications. Connect your load to the output terminals, ensuring correct polarity with the red terminal as positive and black as negative.
Slowly rotate the voltage adjustment knob clockwise while monitoring the voltage meter until you reach your desired output voltage. The analog meter provides immediate feedback of the actual output voltage. Next, adjust the current limiting knob to set the maximum current your circuit can draw. This protects your circuit from over-current damage. If your circuit draws more current than the limit, the supply automatically reduces voltage to maintain the set current limit. Always verify both meter readings before connecting sensitive components. For dual-supply applications requiring both positive and negative voltages, use the common ground terminal and configure two supplies in series-opposing configuration. If the thermal shutdown activates due to extended high-power operation, allow the supply to cool for 15-20 minutes before resuming operation.
Frequently Asked Questions
What is the difference between the 0-80V and 0-160V ranges on this supply?
The dual-range feature allows you to select between two voltage ranges for optimal resolution and stability. In 0-80V mode, the adjustment knob provides finer control and better resolution for lower voltage applications, making it easier to set precise voltages. In 0-160V mode, you can access higher voltages but with coarser adjustment resolution. Choose 0-80V for sensitive analog circuits requiring precise voltage setting, and 0-160V when you need higher output voltages for power electronics or high-impedance loads. The current rating remains 2A in both ranges.
How does the current limiting feature protect my circuit?
The current limiting feature acts as an automatic circuit breaker. You set the maximum current your circuit is allowed to draw using the current adjustment knob. If your circuit attempts to draw more current than this limit (due to a short circuit or fault), the supply automatically reduces its output voltage to maintain exactly the current limit you set. This prevents excessive current from damaging sensitive components. The voltage meter will show a reduced voltage while the current meter reads your set limit. This is normal protection operation. Once you fix the circuit fault and reduce the current demand, the supply returns to normal operation at your set voltage.
Can I use this supply for battery charging applications?
Yes, the Wanptek WPS1602H is excellent for battery charging. Set the voltage to match your battery chemistry: 12V for lead-acid, 14.4V for lithium, or 1.5V per cell for NiMH. Use the current limiting feature to set the maximum charging current appropriate for your battery capacity. For example, charge a 2000mAh battery at 0.5A-1A maximum current. The analog meters let you monitor charging progress in real-time. The short-circuit protection prevents damage if battery terminals accidentally touch. Always disconnect the battery once fully charged to prevent overcharging damage. Never exceed the battery's rated charging voltage or current specifications.
What does output ripple and noise mean, and why is 5mV important?
Ripple and noise refer to unwanted AC voltage fluctuations superimposed on the DC output. Even a DC supply produces tiny AC variations from the transformer and rectifier circuits. The Wanptek WPS1602H maintains ripple below 5mV RMS, which is exceptionally clean for analog circuits. This matters because sensitive circuits like audio amplifiers, precision measurement instruments, and analog-to-digital converters can pick up this noise and produce distortion or measurement errors. Lower ripple means cleaner power and better circuit performance. Linear supplies like this model naturally produce lower ripple than switching supplies, making them ideal for noise-sensitive applications.
