JOHNSON CONTROLS控制器P78系列介紹
P78 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) 開關(guān)配置。
用于雙壓力應(yīng)用的 P78 系列控制器主要設(shè)計(jì)用作商業(yè)制冷和空調(diào)應(yīng)用中的高壓和低壓組合控制器。
P78 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 P78 Series Controls for dual pressure applications are designed primarily for use as combination high and low pressure controls on commercial refrigeration and air-conditioning applications.
