Electronic Plug-in Brennenstuhl BN-PM231

The Brennenstuhl BN-PM231 electronic plug-in is a compact grey power meter that measures electrical parameters at a single socket. Designed for use with standard 230 V mains, this device provides measurements of current, power (output), voltage, power factor, frequency and efficiency to support energy monitoring and basic electrical diagnostics. Its plug-in form factor allows quick connection between a wall outlet and the appliance to be measured, enabling real-time numeric readouts without permanent installation.

Advantages

The BN-PM231 offers precise measurement of current, voltage and active power suited to household and small-office devices, with a rated current capacity up to 16 A. Its compact plug-in design requires no wiring changes and is easy to relocate between appliances. The device displays power factor and frequency in addition to consumption values, giving a fuller picture of electrical behaviour. Constructed in a grey housing, it integrates unobtrusively into most interiors while providing numeric readouts for immediate assessment.

Suitable for

• Measuring energy consumption of household appliances such as kettles, TVs, computers and chargers
• Monitoring devices in small offices and workspaces to identify high-consumption equipment
• Checking voltage stability and frequency for electronic equipment
• Assessing power factor and efficiency for appliances with motors or switch-mode power supplies

Key specifications

• Input voltage: 230 V
• Rated current: up to 16 A
• Measured parameters: current, power (output), voltage, power factor, frequency, efficiency
• Form factor: plug-in single-socket power meter
• Housing colour: grey

How to use

Insert the BN-PM231 into a compatible 230 V wall outlet and then plug the appliance to be measured into the device. The instrument begins measuring automatically and presents readings on its integrated display. For best results allow the appliance to operate under typical load conditions while viewing the measured values. Switch the connected appliance on and off as needed to compare standby and active consumption. To avoid exceeding the device rating, do not connect loads that draw more than 16 A.

Recommendations

Use the meter indoors and avoid exposure to moisture or extreme temperatures. For accurate assessment, measure appliances during normal operation and allow readings to stabilise before recording results. Do not use the device with permanent hardwiring; it is intended for temporary plug-in monitoring. If uncertain about an appliance’s power draw, check the appliance label and ensure the combined load does not exceed the meter’s rated current.
