AP- Series SSR (APS Photo Relays) is used to switch charge and discharge. We recommend solid state relays for applications where there will be frequent ON/OFF switching.
AP-x Series SSD（APS Photo Relays）用于充电・放电时的切换。对于ON/OFF切换次数较多的用途，建议使用光电耦合器。
1.
Regular operationTurn ON both solid state relays for charge and discharge control. Current flows in both directions.
一般情况下充电・放电控制的光电耦合器均置ON。双向均有电流流过
2.
Over-charge preventionIn order to prevent over charging, the solid state relay on the charge control side turns OFF. On the discharge side, current will flow because there is a diode.
防止过充电 为防止过充电，充电控制侧的光电耦合器变为OFF。由于放电侧有二极管，因此会有电流流过。
3.
Over-discharge preventionIn order to prevent over discharging, the solid state relay on the discharge control side turns OFF. On the charge side, current will flow because there is a diode.
防止过放电为防止过放电，放电控制侧的光电耦合器变为OFF。由于充电侧有二极管，因此会有电流流过。
Charge and discharge control is possible by effectively utilizing the internal diodes of the solid state relay.有效利用光电耦合器内部的二极管，从而可对充电・放电进行控制。
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.
AP-x Series SSD（APSEMI Photo Relays）、10A、20A型继电器用来防止充电时电容产生的冲击电流。要求小型的情况下，建议使用光电耦合器、高电压时为10A、20A型继电器。
During device startup, the inrush current prevention relay turns ON and the main relay turns ON after the capacitor is charged.Effective for protection against inrush currents that occur when charging the capacitor.
启动机器时，用来防止冲击的继电器将会置ON，电容充电后，主继电器将会置ON。对于电容充电时产生的冲击电流，可有效地发挥保护作用。
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对蓄电池单元的绝缘劣化进行监控。单元内部发生绝缘劣化的情况下，置ON时将会有接地电流流过，传感器将会进行检测。由于蓄电池属于高电压，因此适合使用高耐压型APSEMI Photo Relays。
