Audiophiles building TPA3255-based amplifiers love VPower68 for its ultra-low noise floor. The switching frequency is well above the audible range (125kHz), and the built-in EMI filter eliminates that annoying high-pitched whine.
Let’s put VPower68 head-to-head with two market leaders: Mean Well LRS-350 and Delta DPS-350AB. vpower68
| Feature | VPower68 | Mean Well LRS-350 | Delta DPS-350AB | | :--- | :--- | :--- | :--- | | Peak Efficiency | 94.7% | 88.5% | 90.0% | | Ripple & Noise | 30mV p-p | 150mV p-p | 80mV p-p | | Operating Temp | -30°C to 80°C | -20°C to 70°C | 0°C to 50°C | | Protection | OVP/OCP/OTP/SCP | OVP/OCP | OCP/SCP | | Price (USD) | $42 | $38 | $65 | | Feature | VPower68 | Mean Well LRS-350
Verdict: VPower68 is slightly more expensive than Mean Well but offers significantly better noise performance and thermal range. It beats Delta on price while matching or exceeding reliability. Even the best hardware fails if installed incorrectly
The first point of interaction for any user is the interface, and vpower68 excels here by prioritizing intuitiveness over clutter.
