CADAC power supply units are designed to run from a minimum of 208V up to a

maximum of 260V, 50/60Hz a.c. In many parts of the world, the normal single-phase

a.c. supply is 100-127V, this means that the CADAC power supply units must be con-

nected across two of the phases in the three-phase a.c. supply, see 3.3.4 Connect-

ing to a 3-phase outlet

CADAC 8400 switch-mode power supply units are designed to run from a minimum

of 208V up to a maximum of 260V a.c, 50/60Hz.

The 8400 is rated thus +13V@92A, ±18V@44A and 48V@5A. This is sufficient to

supply power to a 3 frame configuration, where 4 frames or more are used, the 8019/

8020 PSUs should be used, see 3.3.7 Switch-Mode Power Supply Units (8019 &

8020).

The a.c. input is connected to the PSU via a 3-core cable, CMA reference 3183TQ –

BASEC approved, rated at 20A.

;733#VZLWFK0PRGH#SRZHU#VXSSO\#XQLW

The 8400 unit is based on one POWER ONE RPMS-ETETGDGD1ETK Power block,

with additional circuitry as shown on CADAC drawing number C3.8397.
