RME DPS-2 - Super Low Noise Linear Power Supply

Super Low Noise Linear Power Supply with Unique μFilter and Sensor Technology

The new DPS-2 is an exceptional linear power supply that boasts not only impressive technical data but also a wide range of unique and highly useful features. For instance, the compact device features two differently filtered outputs. The housing and front panel of the DPS-2 are based on the ADI-2 series, accommodating RME's innovative circuitry design on only half rack width.

Two Outputs

The output Linear is a traditional DC output but is equipped with multi-stage passive and active filtering including a 30,000 μF capacitor bank, a ferrite choke as well as an active output filter with a hybrid voltage regulator.

The second output is based on RME's proprietary μFilter technology. Here the signal from the pre-filtered Linear output is also processed by highly efficient active filters to achieve an exceptionally clean DC output with just a few µV (micro-volts) noise. In addition the output has sensor technology, which measures and adapts the output voltage directly at the DC connector of the supplied DC cable. As a result the output impedance and load regulation are extremely low, thus ensuring a clean output voltage of +12.0 V at 2.5 A load, completely avoiding any load-dependent voltage drops.

Hum-free Operation

The additional use of both a 2-stage HF filter and DC filter on the AC mains side enables the DPS-2 to deliver optimum performance without interference noise. This is also ensured by the 60 VA audio toroidal transformer with additional isolation winding and magnetic tape shielding, guaranteeing absolutely hum- and noise-free operation in any situation.

If necessary the GND lift switch can be used to disconnect DC ground from PE (protective earth) for eliminating humming or buzzing noises. In this case safety is not affected since the primary part and the housing stay firmly connected to PE of the power inlet. In addition the DPS-2 comes with a ground terminal screw connection to earth other devices or to use an earthing other than PE for the audio power supply.
