TAGA Harmony LPS-100 linear power supply
The TAGA Harmony LPS-100 is a linear power supply combining four functions in one device: power noise filtering, selectable DC output, USB power outputs and surge/overload protection. It provides cleaner, more stable power for DC-powered audio and video equipment.
Linear Power Supply
The TAGA Harmony LPS-100 combines four functions in one device: power noise filtering, a linear power supply with selectable DC output voltage, two USB power outputs and surge/overload protection.
Most DC-powered electronic devices rely on inexpensive switch-mode power supplies that operate at high switching frequencies and generate electrical noise. This noise can affect connected equipment and feed unwanted interference back into the AC power network. The LPS-100 replaces these adapters with a high-quality linear power supply, providing cleaner and more stable power.
The two-level noise filtering system reduces electrical interference and helps isolate audio-video equipment from contaminated AC power. Acting as a buffer between the wall outlet and connected devices, the LPS-100 can also help extend the lifespan of connected components.
Key Features
- 4-in-1 design – power noise filtering, linear DC power supply, USB power outputs and surge/overload protection.
- Selectable DC output voltage – 5V, 9V, 12V, 15V, 19V or 24V.
- Two-level noise filtering – separate filtering for AC input and DC/USB outputs.
- 100W toroidal isolation transformer – up to 3A (72W) at 24V DC.
- USB-A and USB-C outputs powered by the built-in linear power supply.
- Digital display showing voltage, current, power and output polarity.
- Surge and overload protection for AC, DC and USB outputs.
- DC output protection against overvoltage and short circuits from connected devices.
Technical Description
The first filtering stage uses a built-in 100W toroidal isolation transformer for the 230–240V AC input. The second stage applies dedicated filtering separately to the DC output and USB ports to further reduce electrical noise.
The LPS-100 features a selectable DC output with six voltage settings and reversible polarity. A digital display provides real-time information about output voltage, current, power and selected polarity.
The protection system combines external and internal AC fuses with dedicated overload, thermal and short-circuit protection for the DC output and USB ports, helping to safeguard both the power supply and connected equipment.
