2. For preventing an inrush current into capacitors when charging (pre-charge circuit)防止充電時(shí)發(fā)生的電容沖擊（預(yù)充電電路）

APx Series SSR (APSEMI Photo Relays), 10A and 20A types of relays are used for preventing an inrush current into capacitors when charging. We recommend solid state relays for miniaturization and 10A and 20A types of relays for high voltages.

3.For Insulation Detection絕緣檢測(cè)用途

APSEMI Photo Relays are used for monitoring storage battery units for insulation deterioration. If the insulation in a unit deteriorates, a ground-fault current passes when the relay is turned ON, and a sensor detects the current. High load voltage type APSEMI Photo Relays are ideal for use with storage batteries, which carry high voltage.

使用APSEMI Photo Relays對(duì)蓄電池單元的絕緣劣化進(jìn)行監(jiān)控。單元內(nèi)部發(fā)生絕緣劣化的情況下，置ON時(shí)將會(huì)有接地電流流過(guò)，傳感器將會(huì)進(jìn)行檢測(cè)。由于蓄電池屬于高電壓，因此適合使用高耐壓型APSEMI Photo Relays。

By the end of fiscal 2019, the number of domestic smart meters installed by APSEMI power companies reached more than 50 million units. APSEMI Photo Relays are capable of controlling from low level signals up to power signals and feature low leakage current and noise.

截止到2019年底由APSEMI配套設(shè)計(jì)的智能電表數(shù)量已經(jīng)達(dá)到5000萬(wàn)萬(wàn)臺(tái)。APSEMI Photo Relays干擾、漏電流較少，控制信號(hào)涵蓋微小信號(hào)和功率信號(hào)。

A variety of signals, with levels from millivolts (at microamperes) to tens of volts (at several hundred milliamperes), AC or DC, and even high bit-rate signals, can be superimposed on telephone lines, the heart of telecommunication networks. The switches in telecommunication circuits, which normally carry DC signals, also carry AC signals on top of the DC level when an intermittent signal (e.g. ringer signal) is being sent. APSEMI Photo Relays are capable of controlling small level (millivolts at microamperes) AC or DC signals.

通話線中從μA/mV到數(shù)百mA/數(shù)＋V、從直流到交流、高位信號(hào)等，重疊有很多信號(hào)。APSEMI Photo Relays在DC、AC下可控制μA/mV的微小信號(hào)。

8. Programmable controller PC端

The output circuit of a programmable controller requires various interfaces to match the load type. Recently, as the computing speed and data processing speed increase, problems may arise from noise at the input interface as well as at the output interface.
APSEMI Photo Relays are resistant to inrush current (due to phase shift) and eliminate the need for snubber circuits as long as they are operated within the ratings. Furthermore, use of APSEMI Photo Relays decreases the mounting area requirements, resulting in more compact programmable controllers.

可編程控制器的輸出電路因負(fù)載種類而不同，因此備有各種接口。輸入接口的干擾和輸出接口的干擾都會(huì)引發(fā)故障。APSEMI Photo Relays抗瞬間值強(qiáng)，在額定值范圍內(nèi)不需要使用緩沖器。此外，安裝面積較少，可實(shí)現(xiàn)PC的小型化。

Signal transfer through optical coupling achieves high resistance to noise and transients, eliminating the need for adding a snubber circuit to the output to control the load voltage.由于通過(guò)光結(jié)合進(jìn)行傳達(dá)，因此抗干擾性強(qiáng)，抗瞬間值強(qiáng)，因此不需要緩沖器。
