Humid Ctrl. Indicates the humidity control method. The System can control the humidity based on the relative humidity (RH) of the return air and the dew point (DewPt) of the return air.

•Relative humidity (RH): The System activates humidification modes based on the difference between the humidify/dehumidify setpoint and the return humidity value.

•Dew point (DewPt): The dew point method corrects for hotspots near the environmental sensors, and is calculated from the temperature and relative humidity of the room air.

–The System activates humidification based on the dew point setpoint and the calculated dew point in the room.

–The dew point setpoint is calculated from the humidification setpoint and the reheat setpoint. If there is no reheat mode, then the cooling setpoint is used.

Example. If the reheat setpoint is 20°C (68°F) and the humidification setpoint is 50%, the dew point setpoint is 27°C (80°F). If the room temperature is 23°C (74°F) and the return humidity is 40% the dew point of the room is 26°C (78°F).

The humidifier demand is calculated as the difference between the actual room dew point and the desired room dew point divided by the sensitivity.

In this example: Demand = (49 - 48) / 2 = 0.5 or 50% demand. The humidifier output will be about 50%.

Note: The System will always use the dew point method when the remote sensor readings are used to control the room environment or if the System is part of a redundant Group.

DX, FM specifications

The American Power Conversion (APC) DX,FM series represents a cutting-edge solution designed for critical power management and uninterruptible power supply (UPS) applications. Aimed at businesses and data centers that require robust power protection, this series balances high-performance capabilities with advanced technology features.

One of the key distinguishing features of the DX,FM series is its modular design. This allows users to scale their UPS system according to their needs, making it suitable for a variety of environments. Whether you're managing a small server room or a large data center, the modular architecture ensures that you can add or remove capacity with ease. This flexibility not only optimizes initial investments but also supports future growth seamlessly.

The series employs advanced battery technology, which extends battery life and enhances overall performance. With intelligent battery management systems, the DX,FM ensures that battery health is monitored in real-time, preventing premature failures and unnecessary replacements. This leads to reduced maintenance costs and maximizes uptime.

Additionally, the DX,FM series features innovative cooling solutions that enhance performance in high-density situations. Efficient thermal management reduces the risk of overheating, keeping valuable equipment operating optimally. This is particularly crucial in data centers where heat generated by servers can create potential disruptions.

Another significant characteristic of the DX,FM series is its sophisticated monitoring and management capabilities. Integrated with state-of-the-art software, users can gain remote access to their UPS units, enabling real-time tracking of performance metrics. This remote monitoring capability allows administrators to proactively manage power usage and ensure that systems are operating within safe parameters.

Furthermore, the DX,FM series is designed with a high level of redundancy. This built-in reliability feature ensures that if one unit fails, others can seamlessly take over, maintaining power supply continuity. This is critical for mission-critical environments where power outages could result in substantial financial losses or data loss.

In summary, the American Power Conversion DX,FM series incorporates modularity, advanced battery technology, effective cooling solutions, and sophisticated monitoring features to deliver an ideal power management solution for various organizations. Its design prioritizes flexibility, reliability, and efficiency, making it an essential investment for any business looking to safeguard its operations against power disruptions.
