本系列儀表采用模塊化設(shè)計(jì)，具有豐富的外部DI/DO模塊、AI/AO模塊、帶T-Flash（TF）卡的事件記錄（SOE）模塊、網(wǎng)絡(luò)通信模塊、溫濕度測(cè)量模塊功能，可實(shí)現(xiàn)電路全功率測(cè)量和開(kāi)關(guān)狀態(tài)監(jiān)測(cè)，具有以太網(wǎng)接口的雙RS485可實(shí)現(xiàn)RS485主站的數(shù)據(jù)拷貝，*進(jìn)行數(shù)據(jù)交換。PROFIBUS-DP接口可實(shí)現(xiàn)高速數(shù)據(jù)傳輸和聯(lián)網(wǎng)功能。

APM series power meters of ACREL are power meters that are designed according to IEC standards and synchronized with international advanced technology.

APM series meters have full power measurement, energy statistics, analysis of power quality and network communications and other functions, are mainly used for comprehensive monitoring of the quality of power supply network.

This series of meters use a modular design, with a rich function of the external DI / DO module, AI / AO module, event recording (SOE) module with T-Flash (TF) card, network communication module, Temperature and humidity measurement module, can achieve full power measurement of electrical circuit and monitoring of switch status, Dual RS485 with Ethernet interface can realize data copying of RS485 master station, eliminating the need for data switching exchange. PROFIBUS-DP interface can realize high-speed data transmission and networking function.

terms of reference from grid supplier:

（1）monitoring voltages: L1-N, L2-N, L3-N. Unominal = 230V;

（2）switching relay output at overvoltage: 2 steps:

 Step 1: 110% of Unominal or 253V - delay 60 seconds (s) ;

 Step 2: 115% of Unominal or 264V - delay 0.1s;

（3）switching relay output at undervoltage:

1-step; 80% of Unominal or 184V - delay 0.2s; Range of settings: U: 10-** of Unominal, step not listed, maybe 1V ot 1%; Delay: 0.05 s to 3s, step - not listed, maybe 1s;

（4）switching relay output at overfrequency

1-step; 50.5Hz - delay 0.1s; Range of settings: F: 50-52.5Hz, step 0.1Hz; Delay: 0.1-0.5s, step - maybe 0.1s;

（5）switching relay output at overfrequency

1- step; 47.5Hz - delay 0.1s; Range of settings: F: 47.5-50Hz, step 0.1Hz; Delay: 0.1-0.5s, step - maybe 0.1s;

（6）Delay for recovering. When DO is on by some of previous reasons, there should be time delay after grid parameter(s) are back in nominal range(s). Time range 1-60s, step 1s

（7）Additional settings. (If they are possible).   

7.1 When Unominal is lower than 60-70%, under and overfrequency monitoring can be disabled

7.2 When overfrequency/underfrequency is happened - the DO should not be recovered automatically, it should wait for some kind of manual/remote restore.
