437 Series II 400 Hz Power Quality Monitor and Energy Analyzer

Key features
• 400 Hz Measurement: By increasing the power frequency to 400 Hz, transformers and motors can be much smaller and lighter than at 50 or 60 Hz, which is an advantage in aircrafts, submarines, space crafts, and other military equipment and hand-held tools. The 437 II model captures power quality measurements for these types of avionic and military systems.
• Power Inverter Efficiency: Simultaneously measure AC output power and DC input power for power electronics systems using optional DC clamp.
• PowerWave Data Capture: Capture fast RMS data, show half-cycle and waveforms to characterize electrical system dynamics (generator start-ups, UPS switching etc.).
• Energy Loss Calculator: Classic active and reactive power measurements, unbalance and harmonic power, are quantified to pinpoint the fiscal costs of energy losses.
• Troubleshoot Real-Time: Analyze the trends using the cursors and zoom tools.
• Highest Safety Rating in the Industry: 600 V CAT IV/1000 V CAT III rated for use at the service entrance.
• Automatic Trending: Every measurement is always automatically recorded, without any set-up.
• System-Monitor: Ten power quality parameters on one screen according to EN50160 power quality standard.
• Logger Function: Configure for any test condition with memory for up to 600 parameters at user defined intervals.
• View Graphs and Generate Reports: With included analysis software.
• Battery Life: Seven hours operating time per charge on Li-ion battery pack.

Locating, Predicting, Preventing and Troubleshooting Power Quality Issues – Up to 400 Hz
Higher power frequencies mean smaller and lighter transformers and motors – a critical concern in avionic and military transport applications where weight is a primary concern. Designed specifically for these environments, the Fluke 437 Series II Power Quality and Energy Analyzer is a must-have for those working in ships, submarines, aircraft, spacecraft and other military vehicles.

Equipped with all the functionalities of the Fluke 435 Series II, the 437 Series II offers the best in power quality and energy analysis all the way to 400 Hz.

 
Power Inverter Efficiency
Power inverters take DC current and transform it into AC current, or vice versa. Solar generation systems usually include an inverter that takes the DC energy from the solar cells and converts it to useful AC power. Inverters can lose performance over time and need to be checked. By comparing the input power with the output power you can determine the system efficiency. The 430 series II can measure the efficiency of such inverters by simultaneously measuring the DC and AC power of a system to determine how much power is lost in the conversion process.

Unified Power Measurement
Previously, only experts could calculate how much energy was wasted due to power quality issues; utilities could calculate the cost, but the required measurement process was beyond the reach of average electricians. With the new, patented Unified Power function of the 430 Series II, you can use one handheld tool to determine how much power is being wasted, and calculate exactly what the extra consumption costs. Fluke's patented Unified Power Measurement System provides the most comprehensive view of power available, measuring:

• Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000
• Detailed Loss Analysis
• Unbalance Analysis

Unbalance Analysis These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy.

AutoTrend - Quickly See the Trend
Unique AutoTrend gives you fast insight into changes over time. Every displayed reading is automatically and continuously recorded without having to set up threshold levels or having to manually start the process. You can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral.

SystemMonitor - Check Performance Against EN50160 with Ease
With a single push of a button, the unique System-Monitor gives you an overview of power system performance, and checks the compliance of incoming power to EN50160 limits or to your own custom specifications. The overview is shown on a single screen, with color-coded bars clearly indicating which parameters fall outside the limits.
