JOHNSON CONTROLS控制器P77系列介绍
P77 系列压力控制器主要设计用于商业制冷和空调应用的高低压切断控制、抽空控制、冷凝器风扇循环和容量控制。
这些控件可用于多个压力范围，并与大多数常用制冷剂兼容。 它们也可用于其他非腐蚀性流体应用。 控件还提供多种不同的电气额定值和单刀双掷 (SPDT) 开关配置。
适用于高压或低压应用的 P77 系列控制器专为商业制冷和空调应用的单一压力控制而设计。
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.
