概览
22238为PS200智能供电电源的充电保护器和外壳，不带内部电池。22238充电控制器可以从太阳能板或交流电源给电池提供安全而最优的充电电流和电压。还可以测量不同的输入、输出以及状态参数，以监测电池在充电和使用中的详细状态。
22238还可接入一个外部电池。由于国际运输的成本和相关规则的限制（禁止发运电池），CSI给用户设计了22238。用户必须从当地购买7-Ahr的Yuasa电池。

技术说明
22238为PS200智能供电电源的充电保护器和外壳，不带内部电池；但包括外接电池线缆。由于国际运输的成本和相关规则的限制（禁止发运电池），CSI给用户设计了22238。用户必须从当地购买7-Ahr的Yuasa电池。
22238是基于微控制器的智能型充电保护器，带两步常电压充电和温度补偿功能，优化电池充电并增加电池的使用寿命。两路输入端子可以接入两个充电电源。最大功率点跟踪算法被纳入太阳能输入以最大程度地利用可用的太阳能充电电源。RS-232和SDI-12端子能够让22238把充电参数传给数据采集器。
22238具有用来保护充电电源、电池、充电保护器和负载设备的几个安全特征。SOLAR – G和CHARGE – CHARGE输入端子都集成限流保护硬件和极性反转保护。
自动防故障的可自动复位的热保险保护CHARGE – CHARGE输入免于灾难性的AC/AC或AC/DC充电电源故障。另一个可自动复位的热保险保护12 V输出端子免于输出负载故障事件的影响。
22238还有电池反接保护功能，以及在全部输入和输出端子上都含有ESD和浪涌防护单元。

Measurements |
|
| -NOTE- | Over -40° to +60°C range |
| Average Battery Voltage | ±(1% of reading + 15 mV) |
| Average Battery/Load Current Regulator Input Voltage |
±(2% of reading + 2 mA) Impulse type changes in current may have an average current error of ±(10% of reading + 2 mA). |
| Solar |
±(1% of reading - 0.25 V)/-(1% of reading + 1 V) 1.0 V negative offset is worst-case due to reversal protection diode on input; typical diode drop is 0.35 V. |
| Continuous |
±(1% of reading - 0.5 V)/-(1% of reading + 2 V) 2.0 V negative offset is worst-case due to two series diodes in AC full-bridge. Typical diode drops are 0.35 each for 0.7 V total. |
| Charger Temperature | ± 2°C |
