斷路器分析

• 分析馬達與線圈的運作
• 測定線圈電阻
• 測定最低動作電壓
• 欠壓釋放測試

可輕易對測試結果進行分析，清楚反映線圈、馬達及機械部件的狀態，並有助於發現繞組之間的故障。
強大的電壓源
全新開發的電壓源採用最先進的電力電子技術。由於採用合成輸出技術，令該電源不受電網干擾影響，因此可在完全一致的條件下進行測試，方便直接比較測試結果。
主要特點

• 可變測試電壓，具備高穩定性，最高可達 270 VAC / 300 VDC
• 最大輸出電流達 40 A
• 三組輸出端用於分閘/合閘線圈，一組輸出端用於馬達
• 各輸出端的電壓與頻率可獨立設定
• 具備短路保護與過載保護功能

無需冷卻間隔的長時間輸出
EPOS MC4 的電子式穩壓電源幾乎無損耗，即使在最大輸出功率下也僅產生極少熱能。這使得系統能夠在長時間內輸出高電壓與高電流而無需冷卻階段，與傳統系統相比大幅節省時間與成本。
柔性啟動
在馬達電流輸出時，為避免過高啟動電流導致系統自動關閉，EPOS MC4 可透過「柔性啟動」功能限制湧入電流。
使用者可設定階梯式的啟動電壓曲線，由多個步階與時間組成，從 0 緩升至標稱電壓值。
簡易直覺的操作介面
EPOS MC4 配備一體化操作單元，包含 5 吋觸控螢幕、旋鈕、功能鍵與觸發鍵：

• 所有設定一目了然地顯示
• 可直接編輯測試參數
• 即時顯示輸出值
• 透過 LED 顯示運行狀態

EPOS MC4 與 ACTAS 的整合
EPOS MC4 具備與 ACTAS 測試設備連接的介面。透過 ACTAS 測試軟體，EPOS MC4 可作為電源模組整合於開關設備測試中，以實現自動化測試流程與完整的測試結果分析。
堅固耐用的測試裝置
EPOS MC4 置於堅固耐撞擊的防護硬殼中。當外殼關閉時，其防水防塵等級達 IP67，即使受到強烈衝擊也不會損壞，能可靠保護內部精密電子元件。箱蓋內亦設有建電纜收納處，可容納所附的完整電纜組。這款堅固的測試系統無論在現場、產線或實驗室皆適用。
測試結果的儲存與分析
測試結果會附帶日期與時間標記儲存於內部記憶體中。
透過電腦或筆記型電腦搭配使用者友善的 EPOS MC4 軟體，可下載並管理測試資料。
測試結果可生成報告或匯出為 Excel 試算表，同時亦可將資料儲存在軟體中，以便未來維護與保養時進行比較。

EPOS MC4 – Motor and Coil Test System for Circuit Breaker Testing
EPOS MC4 is a compact, portable motor and coil test system with a particularly powerful AC/DC source.
EPOS MC4 is used to supply power to motors and trip coils and can be used as a battery substitute in switchgear and as a power supply during tests with ACTAS switchgear test systems.
The test system records the operating currents of spring winding and pump motors as well as trip coils and presents the numerical results of the motor and coil currents on the display.
Circuit breaker analysis

• Analysis of motor and coil operation
• Determination of the coil resistance
• Determination of the minimum operating voltage
• Tests for undervoltage releases

It is easy to analyse the results which can give a good indication of the state of coils, motors and mechanical parts or point to faults between windings.
Powerful voltage source
The newly developed voltage source uses state-of-the-art power electronics. Thanks to the synthetic generation of output quantities, the source is unaffected by disturbances in the power supply.  This means that tests can always be carried out under identical conditions, allowing direct comparison of the results.
Special features

• Variable test voltages with high voltage stability up to 270 VAC / 300 VDC
• Maximum currents up to 40 A
• Three outputs for opening/closing coils, one output for the motor
• Outputs are independently configurable with regard to voltage and frequency
• Short-circuit proof and overload-protected

Unlimited output duration without cooling phases
The electronically regulated source of the EPOS MC4 is practically loss-less and generates very little heat, even at maximum output power. This means that high currents and voltages can be output for almost unlimited periods of time without cooling phases, resulting in significant savings in time and money in comparison with conventional systems.
Soft startup
For the motor current output, it is possible to limit high inrush currents, which can lead to the EPOS MC4 switching off, by means of a soft start.
A step-shaped ramp can be parameterized for the startup, which consists of a number of steps and a step time and increases from 0 to the nominal voltage value.
Simple and intuitive operation
For operation and control of the EPOS MC4, an operating unit with 5“ touch screen, jog wheel, function and trigger keys is integrated:

• All settings are clearly displayed
• Test parameters can be edited directly
• Display of output values
• Additional display of operational status via LEDs

EPOS MC4 and ACTAS
EPOS MC4 is equipped with interfaces for connection to ACTAS test devices. Via the ACTAS test software, EPOS MC4 can be conveniently integrated as a source in switchgear tests. Automated test sequences and comprehensive analysis of test results are thus easily possible.
Measuring technology in robust packaging
EPOS MC4 is housed in a handy, extremely robust and resistant hard case. Waterproof and dustproof to IP67 when closed, the case absorbs even hard impacts without damage and reliably protects the test system‘s valuable electronics. And even the case lid has a special feature to offer. The cable compartment integrated into it offers sufficient space for the cable set supplied.
The robust test system is just as suitable for use on site as it is for use in production or in the laboratory.
Saving and evaluating test results
The test results are saved in the internal memory with a time and date stamp.
The data saved in the device can be downloaded and managed with the aid of a PC or laptop and the user-friendly EPOS MC4 software.
The measurement results can be presented in a report or exported to an Excel spreadsheet. It is also possible to save the test data in the software, ensuring that it can be made available for com-parison when future maintenance and servicing is required.
