Megger MLLF Low Level Filter

Megger MLLF Low Level Filter — Clean Low-Level Signals for Relay Testing

The Megger MLLF is a low-level filter accessory designed to interface and filter the low-level voltage outputs of modern relay test sets. Used with Megger SMRT and FREJA relay test systems, it conditions Rogowski-coil and voltage-generator outputs to deliver clean, accurate low-level signals for testing modern protection relays and merging units.

Key Features

• Low-level output filtering — filters the low-level Rogowski and voltage-generator outputs of the latest relay test sets.
• Multiple ranges — Rogowski outputs of 2 V, 10 V and 40 V, plus a 0–2 V low-voltage mode.
• High accuracy — typically ±0.05% of reading + 0.02% of range on the 10 V and 40 V ranges.
• Relay test set compatibility — works with Megger SMRT series and FREJA 500 series (VIGENS 3.5.1 or higher).
• Rugged & compact — UL94 V0 enclosure, IP20, 148 × 141 × 66 mm, ~0.45 kg per unit.
• Supplied as a set — three filters per set for three-phase signal conditioning.
• Standards compliant — EN 61010-1, EN 61326-2-1 and IEC 60068 series.

Applications

The MLLF is used by protection and relay-test engineers to condition the low-level outputs of SMRT and FREJA relay test sets — enabling accurate, low-noise testing of modern protection relays, merging units and low-energy analogue inputs.
