Features Power measurement The power measurement is performed by a specially developed circuit which is capable of measuring the waveform of the voltage and current signals on the output of a frequency inverter. The unit contains a 4 step programmable analogue filter and 3 digital filters which may be used to improve accuracy at frequencies down to 10Hz. Voltage measurement The APM382 is suitable for mains voltages from 3x230V to 3x575V. The integrated measurement system is designed for measuring after frequency inverters - i.e. between the frequency inverter and the motor. Hence the APM382 is not powered by the measuring voltage like the majority of the Unipower products, but by a 24Vdc. One of 7 mains voltage ranges is selectable from the front plate. Current measurement The APM382 directly measures up to 80A with internal CTs. To take advantage of the large measurement range, the unit has 10 current ranges making APM382 suitable for nominal currents below 1A and up to 80A. The current range is set by a selector switch on the front plate. Analogue output The APM382 features voltage and current outputs configurable as 0- 20mA (0-10V) or 4-20mA (2-10V). It is not possible to generate 0-10V Technical Specifications and 4-20mA simultaneously. 20mA (10V) is generated at nominal current, nominal voltage and cos?=1. Selecting an invalid voltage range results in both outputs set to 0mA (0V). Both outputs may be inverted for use in a control loop. Digital inputs The unit is equipped with 6 digital inputs. In the standard version only S1 - S5 are used. All digital inputs are activated (On) when connected to the +12 output (23), or an external +12-24Vdc source. Digital outputs 3 optocoupler outputs (Out1, Out2, Out3) are available for signalling alarms. They are On under normal conditions and Off during alarms. The output function may be inverted but is set common for both outputs. If an invalid voltage range is selected both outputs are set Off. LED indicators The APM382 has 4 LED indicators. The LED marked ?Load“ indicates that the 24Vdc is connected. If the measured load is below 3% of the measurement range this LED flashes. The LED marked ?Aux“ is used as indicator for the start timer (Ts) as well as a dP/dt-alarm. The LEDs marked ?Limit 1“ and ?Limit 2“ flash concurrently, if an invalid voltage range is selected, but otherwise indicate the status of the two limits; LED On = Tr active, LED flashing = Alarm

Installation The APM382 is connected to the mains and load as shown in the drawing above. The example is shown where a frequency inverter is used. If this is not the case, L1, L2 and L3 are connected directly to the mains. The three motor cables are lead through the tubes mounted in the unit. Each tube is encircled by a special CT capable of measuring currents linearly up to 130A. The CTs can withstand start-up currents up to 500A. For correct measurement the live wires must be lead through the correct tube as shown in the drawing. The direction of the current is not important but must be the same for all three phases. Measurement Range Setting up the measurement range in the APM382 is done choosing nominal current and voltage. Based on this the power range may be calculated according to: PRange = √3 * U * I All setpoints are enterred in % of the measurement range and the analogue outputs are also directly proportional to it as well; 20mA (10V) corresponds to a measurement of PRange kW. Setup All parameters in the APM382 are setup using a PC with the software 382Mon. (See users guide about how to install and use 382Mon). The basic setup of APM382 consists of the parameters: Timer range : 100s or 1000s (2 decimals or 1) Start timer (Ts) : 0,01 - 999,9s Iout : 0-20mA or 4-20mA (0-10V or 2-10V)

安裝 APM382 連接到主電源和負(fù)載，如上圖所示。該示例顯示了使用變頻器的情況。如果不是這種情況，L1、L2 和 L3 將直接連接到電源。三根電機(jī)電纜穿過安裝在裝置中的管子。每個管子都被一個特殊的 CT 包圍，能夠線性測量高達(dá) 130A 的電流。 CT 可承受高達(dá) 500A 的啟動電流。為了正確測量，火線必須穿過正確的管子，如圖所示。電流的方向并不重要，但所有三相必須相同。測量范圍 在 APM382 中設(shè)置測量范圍是通過選擇標(biāo)稱電流和電壓來完成的。在此基礎(chǔ)上，功率范圍可以根據(jù)以下公式計算： PRange = √3 * U * I 所有設(shè)定點(diǎn)都以測量范圍的百分比輸入，模擬輸出也與其成正比； 20mA (10V) 對應(yīng)于 PRange kW 的測量值。設(shè)置 APM382 中的所有參數(shù)均使用帶有 382Mon 軟件的 PC 設(shè)置。 （有關(guān)如何安裝和使用 382Mon 的信息，請參閱用戶指南）。 APM382 的基本設(shè)置包括以下參數(shù)： 定時器范圍：100s 或 1000s（2 位小數(shù)或 1） 啟動定時器 (Ts)：0,01 - 999,9s Iout：0-20mA 或 4-20mA（0-10V 或 2 -10V)
