JOHNSON CONTROLS控制器P77系列介紹
P77 系列壓力控制器主要設(shè)計(jì)用于商業(yè)制冷和空調(diào)應(yīng)用的高低壓切斷控制、抽空控制、冷凝器風(fēng)扇循環(huán)和容量控制。
這些控件可用于多個(gè)壓力范圍，并與大多數(shù)常用制冷劑兼容。 它們也可用于其他非腐蝕性流體應(yīng)用。 控件還提供多種不同的電氣額定值和單刀雙擲 (SPDT) 開(kāi)關(guān)配置。
適用于高壓或低壓應(yīng)用的 P77 系列控制器專(zhuān)為商業(yè)制冷和空調(diào)應(yīng)用的單一壓力控制而設(shè)計(jì)。
P77 Series Pressure Controls are designed primarily for high and low pressure cut-out control, pump-down control, condenser fan cycling, and capacity control on commercial refrigeration and air-conditioning applications.
These controls are available in several pressure ranges and are compatible with most common refrigerants. They may also be used on other non-corrosive fluid applications. Controls also are available in several different electrical ratings and single-pole, double-throw (SPDT) switch configurations.
The P77 Series Controls for high or low pressure applications are designed for single pressure control of commercial refrigeration and air-conditioning applications.
