Marsden M-550 Adaptor, Power Supply for M-550 Digital Stand on Scale
- Medical-grade mains power adaptor designed exclusively for the Marsden M-550 GP floor scale, enabling continuous mains-powered operation in fixed GP surgery, pharmacy and clinic locations without dependency on the 4×AA battery supply.
- Eliminates battery replacement interruptions in high-frequency GP surgery use, where the M-550 may be in continuous daily operation across multiple consulting rooms and battery management creates a recurring operational overhead for practice management.
- Manufactured to the correct voltage and current specification for the M-550 indicator, maintaining Class III calibration accuracy and MHRA device compliance that third-party adaptors of incorrect specification cannot reliably guarantee for a certified clinical device.
- Recommended spare for NHS GP practices and clinics operating the M-550 as a primary patient weighing scale, ensuring scale operational continuity and eliminating the scale downtime risk associated with a missing or damaged original adaptor in a busy clinical environment.
Marsden M-550 Adaptor: Medical-Grade Mains Power Supply for the M-550 GP Floor Scale
The Marsden M-550 Adaptor is the manufacturer-approved mains power supply for the M-550 digital GP floor scale, enabling fixed-location clinical operation without battery dependency in GP surgeries, pharmacies and outpatient clinics where the scale is in daily use across multiple consulting sessions. Mains operation eliminates the battery management overhead that arises when the M-550 is the primary patient weighing scale in a high-frequency consultation environment, ensuring the scale is always powered and ready without the interruption risk of depleted batteries during a consultation session.
As a Marsden-designed adaptor specific to the M-550 indicator, it delivers the correct voltage and current specification required to maintain Class III weighing accuracy and MHRA medical device compliance throughout operation.

Regulatory and Clinical Compliance
The Marsden M-550 is a Class III Approved medical device under the NAWI Directive, and MHRA medical device guidance requires that replacement power supplies for approved clinical devices are manufacturer-specified components matched to the device's electrical specification. Using a third-party adaptor of incorrect voltage or current output risks compromising the M-550's internal electronics, affecting calibration accuracy and potentially invalidating the Class III certification for clinical diagnostic use. The Marsden M-550 Adaptor is the correct specification component that maintains the device's certified clinical performance and MHRA compliance throughout its operational life.
Frequently Asked Questions
Does switching from battery to mains operation require the M-550 to be reverified?
No. Switching between battery and mains power using the manufacturer-specified adaptor does not affect the M-550's Class III calibration and does not require reverification. The scale's weighing mechanism and load cells operate identically regardless of whether power is supplied by battery or mains adaptor. Reverification is only required when the weighing mechanism or load cells have been serviced, the scale has been involved in a significant impact, or the scale is due its scheduled periodic reverification under the practice's medical equipment management programme.
Is the M-550 Adaptor safe to leave plugged in when the scale is not in use?
Yes. The M-550 Adaptor is a medical-grade power supply designed for clinical environments and is safe to leave connected to the mains when the scale is not actively in use. The scale's auto power-off function operates independently of the adaptor connection, powering down the indicator after the configured idle period while the adaptor remains connected. This arrangement means the scale is immediately ready for use when a patient presents without requiring battery status checks before each consultation.
