GM6-PAFB

Description

AC mains power module for GM6 racks, intended when analog or TC modules are present. Provides the 5 V rail with higher capacity and supports analog module rails per OEM guidance.

The Polar Energy Assessment:

GM6-PAFB is the GM6 family AC power option recommended when you plan to use analog modules (A/D, D/A, TC inputs) on the rack. LS / GLOFA documentation explicitly calls out PAFB as the appropriate choice for analog modules because it supplies the required internal currents and rails that standard low-capacity power modules cannot reliably provide. It accepts standard AC mains (100–240 VAC per regional SKU tables) and includes the 5 VDC rail sized for GM6 analog + digital module mixes.

Pros

• Designed and recommended by OEM specifically for racks with analog/thermocouple modules.
• Higher 5 V rail capacity than basic PAFA types, reduces risk of brownouts with many modules.
• Standard AC input, easy swap into GM6 main power slot.

Limitations

• AC mains input only (verify line voltage variant before ordering).
• Legacy module.

Typical use cases

• Any GM6 rack that will host analog input/output modules (for example G6F-AD2A / G6F-DA2V) or thermocouple (TC) modules; central plant racks with mixed analog + digital I/O. Use when analog / TC modules are installed; supplies required internal currents.
