产品描述

SR489-P5-HI-A20 是 GE Multilin 制造的发电机管理继电器，是 489 发电机管理系列的一部分。该继电器具有 5A 相 CT 次级和 90-300 VDC 和 70265 VAC （48-62 Hz） 的 HI 控制功率。该继电器上的模拟输出为 4 至 20 mA。这款 489-P5-HI-A20-E 继电器具有增强的显示屏，其 LCD 比基本显示屏更大，通常用作 489-P5-HI-A20 基本显示屏版本的升级版。

SR489-P5-HI-A20是 489 发电机保护系列中安装最多的继电器，因此是一款高要求继电器。继电器内置了489-P5-HI-A20-E的以下功能。

跳闸和报警保护

计量

断路器故障

闪存

脱扣线圈监控

VT 保险丝故障

模拟

489 Enervista 489PC 软件与 SR489-P5-HI-A20 一起使用，允许用户从 PC 对继电器进行交互和编程。本软件包含在SR489-P5-HI-A20的新工厂软件包版本中。此外，新款 SR489-P5-HI-A20 随附一个 SR489-CASE 抽出式外壳，并可根据要求与翻新继电器一起提供。有关 489-P5-HI-A20-E 的手册和其他制造商文档可从 GE Power Management 和 GE Multilin 获得。

Product description

The SR489-P5-HI-A20 is a generator management relay manufactured by GE Multilin and is part of the 489 generator management family. The relay has 5A phase CT secondary and HI control power of 90-300 VDC and 70265 VAC (48-62 Hz). The analog output on this relay is 4 to 20 mA. This 489-P5-HI-A20-E relay features an enhanced display with a larger LCD than the base display and is often used as an upgrade to the 489-P5-HI-A20 base display version.

The SR489-P5-HI-A20 is the most installed relay in the 489 generator protection series and is therefore a highly demanding relay. The relay has the following functions built into the 489-P5-HI-A20-E.

Trip and alarm protection

measure

Circuit breaker fault

Flash memory

Trip coil monitoring

The VT fuse is faulty

The 489 Enervista 489PC software is used with the SR489-P5-HI-A20, allowing users to interact and program relays from a PC. This software is included in the new Factory package version of SR489-P5-HI-A20. In addition, the new SR489-P5-HI-A20 comes with an SR489-CASE draw-out housing and is available on request with a refurbished relay. Manuals and other manufacturer documentation for the 489-P5-HI-A20-E are available from GE Power Management and GE Multilin.
