KMC執(zhí)行器MEP-48系列描述
These compact but powerful direct-coupled actuators provide tri-state or proportional control for small dampers or valves in HVAC systems. A minimum torque of 40 (MEP-40xx) or 80 (MEP-48xx) inch-pounds is available over the 95° angular rotation.
The MEP-4002/4022/4802/4822 proportional actuator models accept a 0-10 or 2-10 volts DC control signal input from a thermostat, controller, or building automation system. “Anti-jitter” circuitry significantly reduces hunting and needless wear on the actuator and valve packing or damper components (from unnecessary miniscule position changes caused by undamped analog input signals). A user-initiated, auto-mapping feature provides better equipment control by reassigning the 0-10 or 2-10 volts DC input signal range over a reduced rotation range (from 45° to 95°). These models also feature a switch-selectable, 1–5 or 2–10 (or 0–5 or 0–10) VDC voltage feedback output that is proportional to the actuator position.
The MEP-4001/4003/4013/4021/4801/4813/4821 tri-state/two-position models are designed for use with floating thermostats, controllers, or building automation systems. The MEP-4013/4813 models feature a 10,000 ohm (+/- 10%), three-wire potentiometer feedback output. (The tri-state MEP-4003/4003V do not have two-position functionality or the larger green top enclosure.)
The MEP-4×21/4×22 models also have a fully adjustable, built-in SPDT auxiliary switch, for remote position indication or controller and equipment interface.
MEP-4001V/4002V/4003V actuators have brackets with a patented, quick-mounting mechanism that mounts directly on VFB-43…BC and VFB-46…BC series valve bodies (or VFB-43…BX and VFB-46…BX series with HPO-5074 kit). (See the “V” Models Valve Cross-Reference section in the data sheet for more information.)
All other MEP-4000s mount directly to 1/4- to 5/8-inch (6 to 16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm) square shafts, eliminating the need for expensive and complicated linkages. A non-rotation bracket, to prevent lateral movement, is included with each actuator. A gear disengagement feature allows manual positioning of the actuator.
For fail-safe versions of these actuators, see the MEP-4200/4500/4900 series. See also the modular MEP-4042/4842 and the fast-operating 10 in-lb. MEP-4101.
這些緊湊但功能強(qiáng)大的直接耦合執(zhí)行器為 HVAC 系統(tǒng)中的小型阻尼器或閥門提供三態(tài)或比例控制。 在 95° 角旋轉(zhuǎn)范圍內(nèi)，最小扭矩為 40 (MEP-40xx) 或 80 (MEP-48xx) 英寸磅。
MEP-4002/4022/4802/4822 比例執(zhí)行器型號(hào)接受來(lái)自恒溫器、控制器或樓宇自動(dòng)化系統(tǒng)的 0-10 或 2-10 伏直流控制信號(hào)輸入。 “抗抖動(dòng)”電路顯著減少了執(zhí)行器和閥門密封件或阻尼器組件上的擺動(dòng)和不必要的磨損（由無(wú)阻尼模擬輸入信號(hào)引起的不必要的微小位置變化）。 用戶啟動(dòng)的自動(dòng)映射功能通過(guò)在縮小的旋轉(zhuǎn)范圍（從 45° 到 95°）內(nèi)重新分配 0-10 或 2-10 伏直流輸入信號(hào)范圍來(lái)提供更好的設(shè)備控制。 這些型號(hào)還具有開關(guān)可選、1-5 或 2-10（或 0-5 或 0-10）VDC 電壓反饋輸出，與執(zhí)行器位置成比例。
MEP-4001/4003/4013/4021/4801/4813/4821 三態(tài)/二位型號(hào)設(shè)計(jì)用于浮動(dòng)恒溫器、控制器或樓宇自動(dòng)化系統(tǒng)。 MEP-4013/4813 型號(hào)具有 10,000 歐姆 (+/- 10%)、三線電位器反饋輸出。 （三態(tài) MEP-4003/4003V 沒有兩位功能或更大的綠色頂部外殼。）
MEP-4×21/4×22 型號(hào)還有一個(gè)完全可調(diào)的內(nèi)置 SPDT 輔助開關(guān)，用于遠(yuǎn)程位置指示或控制器和設(shè)備接口。
MEP-4001V/4002V/4003V 執(zhí)行器的支架帶有獲得專利的快速安裝機(jī)構(gòu)，可直接安裝在 VFB-43…BC 和 VFB-46…BC 系列閥體（或 VFB-43…BX 和 VFB-46…BX 系列）上 帶 HPO-5074 套件）。 （有關(guān)更多信息，請(qǐng)參見數(shù)據(jù)表中的“V”型閥門交叉參考部分。）
所有其他 MEP-4000 直接安裝到 1/4 至 5/8 英寸（6 至 16 毫米）圓軸或 1/4 至 7/16 英寸（6 至 11 毫米）方軸上，無(wú)需 昂貴而復(fù)雜的聯(lián)系。 每個(gè)執(zhí)行器都包含一個(gè)非旋轉(zhuǎn)支架，以防止橫向移動(dòng)。 齒輪脫離功能允許手動(dòng)定位執(zhí)行器。
