3.7. DC Power Supply

The DC power supply can be at any voltage in the range defined in Chapter 5: Technical

Specifications. The supply source must comply with the safety aspects of the relevant

requirements, in accordance with the most recent version of the standard EN60950 or

equivalent Low Voltage Directive Standard, all according to the applicable over-voltage

category. If the power source to the power supply is the AC line (through a transformer), safety

margins must be considered, in order to avoid activating the under/over voltage protection due

to line variations and/or voltage drop under load.

In addition to the above, the transformer must comply with the safety aspects of the relevant

requirements in accordance with the most recent version of the standard EN60742 (Isolating

and Safety Isolating Transformers). The nominal DC bus voltage should be in the following

range:

1.2 V

dcmin

< V

< 0.9 V

dcmax

where:

dcmin

is the minimum DC bus

dcmax

is the maximum DC bus

The recommended minimum power supply capacitance for single-phase connections is as

follows:

Amplifier Voltage Range 50 - 55 V 100 V 200 V

Recommended capacitance 5600 μF 3300 μF 1500 μF

The transformer power should be calculated such that it will be able to deliver power to the

amplifier (including peak power) without significant voltage drops.

The power supply should be located as close as possible to the amplifier. The maximum

distance is 30 cm (1 foot). While driving high-inertia loads, the power supply must be equipped

with a shunt regulator; otherwise, the amplifier will be disabled whenever the capacitors are

charged above the maximum voltage.
