imPULSE SMPS6060-PFC SWICHTING MODE POWER SUPPLY

The imPULSE SMPS6060PFC power supply is designed to power the different imPULSE audio series amplification modules, so we can connect different types of amplifiers using a single supply.
The imPULSE SMPS6060PFC efficiency is very high, so we can get a high performance in a very short area.It is a switching quasi-resonant supply working in half-bridge mode. It delivers a 1000W sustained output and a 2000W peak output thanks to the use of a tuned circuit at the output. This circuit makes the waveform of the signal current that runs through the power transistors sinuoidal and not square as usual. This way, we get a very high efficiency so the transistors must dissipate much less heat.The oscillation frequency is about 125kHz and the circuit ensures a soft start at turning on to prevent false triggering of external fuses and circuit breakers.
It has a protection against overcurrent based in an output current real-time reading. Any anomaly produces a silent supply turn-off , which rearms automatically without user intervention.
The imPULSE SMPS6060-PFC delivers two output voltages: +/- 80V for imPULSE D600 modules and +/-30V for imPULSE D200 modules. It also has an +/- 12V 1A output for auxiliar circuits, DSP processors … and a +12V 1A dedicated output for external fans.
The active PFC (Power Factor Correction) circuit at the A.C. input keeps the radiation produced by the circuitry under the specification and regulation levels, and provides a better voltage stabilization in case of fluctuations in the mains supply.

- Self-amplified audio systems powering
- Amplified racks powering

imPULSE D-200 CLASS D AUDIO AMPLIFIER

The imPULSE D200 is a Class D amplification module developed by Red Rocks Audio for self-amplified professional audio purposes.
This new technology is based in the use of high frequency switching power devices, which provides a very high performance and very low losses. With an amazing efficiency (more than 93%) the imPULSE D200 module transforms almost the total power supply energy into audio power, with minimum heat losses. This way, the heatsink could be smaller, saving space and materials.
The imPULSE D200 real power is 200W RMS at 8Ω and 140W RMS at 16Ω. It also works with 4Ω loads, although its maximum power is limited to 200W by the included overcurrent protection.
The amplifier operation is constantly monitored through integrated protection circuits. In case of a short circuit in the audio output or a load abnormal behaviour, a high-speed circuit protects the power transistors in a silent manner. Another protection acts in case of an input voltage increasing or decreasing to dangerous values. At last, there’s another protection that detects any offset or continuous voltage present in the audio output.
The imPULSE D200 modulation system uses a self-oscillating high frequency circuit that does not require an external clock. Also, the used feedback includes the reconstruction output filter in the loop. This way, the amplifier can correct load anomalies or defects at real time without using additional filters or zobels at the output, making the frequency response constant at any time, not influenced by load type or impedance. This means that we can turn the module on without any load and the input signal frequency won’t affect the amplifier operation. Other implementations need to waste a lot of energy through a zobel in the output when the input signal goes up to 10kHz and it’s constant, and even shuts down to prevent the damage of the output transistors.
Because its small size and low heat losses, this module is ideal for compression HF drivers and active boxes where space is important.

Applications:

- Active speakers system for touring (line-arrays, monitors, side-fills, etc.)
- Self-amplified studio monitors
- Loudspeaker systems for public address, concert systems, etc.

Power Supply Hypex electronics smps180v2

The SMPS180 is a high efficiency Safety Class 2 switch mode power supply specifically designed for
use with our range of UcD™ amplifier modules. Key features are high efficiency over the entire load
range, universal input voltage range (85 – 264V, 50 – 60Hz), near unity Power Factor, low weight and
very low radiated and conducted EMI. The SMPS180 also features an advanced overcurrent
protection which in case of temporary overload simply reduces the output voltage, only when the
overload condition remains for a longer time the supply will enter hiccup mode until the overload
condition disappears. This feature in combination with the advanced feedback topology and large
secondary bulk storage output caps leads to the capability of delivering high dynamic headroom
power to the connected amplifier. The SMPS180 also includes an auxiliary isolated ±12V supply and
a control circuit directly interfacing with our range of (OEM and standard) UcD™ amplifier modules.
The supply is triggered for normal operation or latched off in case of critical fault via in built-in
actuators. The SMPS180 is optimized from the first phase of design to final implementation to
realize the low EMI signature required of the most demanding audio applications.
