PM330 Power Module, degree of protection IP20, frame size GX

PM330 Power Modules have been specifically developed for driving pumps, fans and compressors with quadratic characteristic for use in HVAC applications. They have a connection to an external Braking Module (1-quadrant applications). The Power Modules can be installed very flexibly in customer-specific cabinets with the associated system components.

The PM330 Power Modules produce only low apparent power losses. In addition to the energy-related advantages, environmental stressing is also reduced.

To reduce emissions, the PM330 Power Modules are equipped with a radio interference suppression filter as standard (in accordance with the limit values defined in Category C3). The PM330 Power Modules equipped with a line filter also meet the limits for use in the first environment (Category C2) as specified in EN 61800‑3 1).

The PM330 Power Modules are designed for connection to grounded TN/TT systems and non-grounded IT systems.

PM330 Power Modules do not support Control Units with Safety Integrated. Safety functions can be implemented by means of external switching devices.

1) To comply with Category C2, shielded cables must also be used between the inverter and motor with a maximum permissible cable length of 100 m. Longer cables can be used if output reactors and output filters are connected (see section Load-side power components).

Характеристика



Derating data

The PM330 Power Modules and the associated system components are rated for an ambient temperature of 40 °C and installation altitudes of up to 1000 m above sea level. At ambient temperatures of > 40 °C, the output current must be reduced. Ambient temperatures above 50 °C are not permissible.

At installation altitudes > 1000 m 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 up to 4000 m, 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 40 °C and are reached at any time by the automatic adaptation of the output pulse frequency.

Current derating as a function of the ambient temperature

Low overload (LO) and high overload (HO) for PM330 Power Modules

Note:

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

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

Rated power as a function of the 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 inverters with a PM330 Power Module. The purpose of this aid is to ensure the constant reliable operation of the inverter, 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 inverter 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 inverter service life; no overload reaction triggered by the thermal monitoring model on condition of compliance with the duty times specified in the diagram.

Overload capability

PM330 Power Modules have an overload reserve e.g. to handle breakaway torques. If larger surge loads occur, this must be taken into account when configuring. In drives with overload requirements, the appropriate base-load current must, therefore, be used as a basis for the required load.

The unit can operate in two different duty cycles in the permissible continuous operating range shown in the diagram (green area). Depending on how the system is dimensioned, the relevant base-load current is effective as a rated quantity.

The criterion for overload is that the drive is operated with its base-load current before and after the overload occurs on the basis of a duty cycle duration of 300 s.

The base-load current for a low overload IL is the basis for a duty cycle of 110 % for 60 s or 135 % for 3 s.

The base-load current IH for a high overload is based on a duty cycle of 150 % for 60 s.

1) Rated power of a typical 4-pole standard induction motor based on the base-load current IL or IH at 400 V 3 AC/50 Hz (kW) or 460 V 3 AC/60 Hz (hp).

2) The base-load current IL is based on the duty cycle for low overload (LO).

3) The base-load current IH is based on the duty cycle for high overload (HO).

4) The input current depends on the motor load and line impedance and applies for a line impedance corresponding to uK = 1 %. The rated input currents apply for a load at rated power (based on Irated) – these current values are specified on the rating plate.

5) 10 ms value from current-time characteristic for reliable tripping of installed protection devices.

Note:

If the minimum short-circuit current is not reached, the activation time of the fuses is increased, which can lead to damage.
