⁵⁾ 10 ms value from current-time characteristic for reliable tripping of installed protection devices. If the minimum short-circuit current is not reached, the tripping time of the fuses is increased, which can lead to damage.

Derating data

The PM330 Power Modules and the associated system components are rated for an ambient temperature of 45 °C (113 °F) and installation altitudes of up to 1000 m (3281 ft) above sea level. At ambient temperatures of > 45 °C (113 °F), the output current must be reduced. Ambient temperatures above 55 °C (131 °F) are not permissible.

At installation altitudes > 1000 m (3281 ft) above sea level, it must be taken into account that the air pressure, and therefore air density, decreases as the height increases. As a consequence, the cooling efficiency and the insulation capacity of the air also decrease. Due to the reduced cooling efficiency, it is necessary, on the one hand, to reduce the ambient temperature, and on the other hand, to lower heat loss in the built-in unit by reducing the output current.

As additional measure for installation altitudes from 2000 m (6562 ft) up to 4000 m (13123 ft), an isolating transformer is required in order to reduce transient overvoltages according to EN 60664‑1.

Automatic adjustment of pulse frequency

In the factory setting, the drive starts with a pulse frequency of 4 kHz and reduces the pulse frequency automatically to the associated required frequencies when loaded. When the load decreases, the pulse frequency is increased automatically up to 4 kHz. The values of the rated current apply to a pulse frequency of 2 kHz and an ambient temperature of 45 °C (113 °F) and are reached at any time by the automatic adaptation of the output pulse frequency.

Current derating as a function of the installation altitude and the ambient temperature

At installation altitudes above 1000 m (3281 ft), the permissible output current can be compensated to a certain extent using the ambient temperature.

The operating temperature ranges of the Control Units must be taken into account (see technical specifications of Control Units).

Current derating as a function of the line voltage

PM330 Power Modules supply a constant power over the full permissible range of line voltage.

The constant power results in current derating as a function of the line voltage.

Operating ranges

An additional dimensioning aid is available for all PM330 Power Modules. The purpose of this aid is to ensure the constant reliable operation of the converter, in particular with regard to service life expectancy.

The dimensioning aid clearly distinguishes between continuous operating ranges and short-time operating ranges. As a result, due consideration can be given to operating ranges when the plant is configured. For further details, please refer to the diagram below and the explanatory text.

Continuous operation (green area) permissible.

Short-time operation (yellow area) permissible for 2 % of the total operating period without significant reduction in the converter service life; no overload reaction triggered by the thermal monitoring model.

Sporadic short-time operation (red area) permissible for only very short, rare operating states lasting less than 0.1 % of the total operating period without significant reduction in the converter service life; no overload reaction triggered by the thermal monitoring model on condition of compliance with the duty times specified in the diagram.
