57C493 电源Lorain Reltec 固件中设置正确的PWM频率

57C493是一款Reliance Electric Automax电源。该电源也可能以 Asea Brown Boveri 和/或 Baldor Reliance 产品线销售，具体取决于其实际生产年份。这些公司都没有仍然维护57C493，可能有点难以追踪。AX Control 确实尽一切努力将其作为翻新零件或新的剩余零件保持库存。

57C493 是一款 376 W 电源模块，输入电压为 100-132 VAC。它的标称输入频率为 50/60 HZ。它的隔离额定值为 1500 VAC 输入到输入或 600V DC 输出到机架。该模块具有固定弹出器、可拆卸端子开关和过压/过流保护功能。 该模块具有保护性铝制机箱和散热器。

57C493 的面板具有一些不同的功能。它有两个 LED，分别标记为 POWER 和 FAULT。它有一个标记为 PROGRAM、MEMORY PROTECT 和 SETUP 的按键开关。它有一个 250V 的可更换保险丝。它有一个备用电池的位置。它还有一个带顶棚的端子排，标有 L2 120VAC L1。此电源在 AutoMax 存储机架上占用三个插槽，并且必须是机架上最左侧的物品。您可以使用一组安装螺钉以及机架和面板上的支架将此电源连接到机架。您还可以在需要时使用面板支架安全地从机架上卸下电源。
