The voltage is Regulated output, input 200V AC or 240V AC. output will same.


Voltage regulation accuracy: ±3% of main no-load, ±10% of load; auxiliary, independent ±1% (at AC220V input)

Continuous power: 1000W (continuous operation at 25°C ambient temperature)

Rated power: 1700W (25 °C ambient temperature can work continuously for about 5 minutes, long-term work plus fan cooling
)

Instantaneous power: 2200W (can work continuously for about 1 minute at 25°C ambient temperature)

Conversion efficiency: Max 98%

Dimensions: length, width and height = 207 * 100 * 45mm

Weight: 700g




LLC soft-switching technology, optimized for the dynamic characteristics of the amplifier design, the effect is better than the Toroid tranformer, the size and weight cost has advantages, high conversion efficiency, output resistance is small, amp dynamic is very good.


All high-frequency low-impedance electrolytic capacitors specifications, low ripple.

Instantaneous output current can reach 5-10 times the normal current, very suitable for high-power amplifier.


Note:

For commercial purposes, the circuit and some components are polished and filled with epoxy resin. No schematic is provided.












Load test:  Load is the our IRS2092-1700W power amplifier board, output 2 ohm resistor, input AC 230V power 2185W.
