characteristics, or c) where the dynamic output response of the power supply is critical to load
performance.

CABLE RECOMMENDATIONS
For power cables (positive and negative) No. 20 or 22 AWG stranded wire is recommended for
each (these sizes fit the plugs supplied for the front panel output connections). The wire insula-
tion must be rated for nominal voltage of the power supply (e.g., 500V for BHK 500-80MG). If a
float voltage is used, the wire insulation must be rated for the nominal voltage of the power sup-
ply plus the float voltage; the DC Isolation Voltage (see Table 1-2, under Output Characteristics)
defines the maximum float voltage allowed. For noisy environments, tied pair (adjacent wires
secured with cable ties) or twisted pair cables are recommended. It is recommended that cable
length not exceed 50 feet; for longer cable lengths, contact Kepco.
Remote sensing is used to accurately control voltage at the load rather than at the output termi-
nals of the power supply (local sensing) by compensating for voltage drop (0.5 V d-c per lead) in
the power cables. For sense cables (positive and negative) No. 22 AWG stranded wire is rec-
ommended for each. For noisy environments, tied pair or twisted pair cables are recommended.
It is recommended that cable length not exceed 50 feet; for longer cable lengths, contact Kepco.

LOAD CONNECTION - GENERAL
Load connections to the BHK-MG 40W Power Supply are achieved via the rear output terminal
strip (TB1); (+) and (-) outputs are also available at the jack located on the front panel. Configu-
ration of the rear output terminal strip is facilitated by five types of links supplied with the unit:
•
2-terminal link: (qty 2)
•
3-terminal link: (qty 2)
•
4-terminal link: (qty 2)
•
5-terminal link: (qty 1)
•
6-terminal link: (qty 1)
These links are used to configure the power supply for local or remote sensing, slow or fast
mode, insertion of the grounding network, isolated (floating) output, and negative or positive
grounded output. The links allow many possible configurations using various combinations of
the configurable parameters noted above.
The BHK-MG 40W Power Supply is shipped from the factory configured as follows (factory
default configuration): local sensing, grounding network connected, slow mode, output isolated
from ground (floating). This configuration is obtained using two 4-terminal links connected as
shown in Figure 2-4.
NOTE: REGARDLESS OF OUTPUT CONFIGURATION, OUTPUT SENSE LINES MUST BE
CONNECTED FOR PROPER OPERATION, EITHER LOCALLY, OR AT THE LOAD
(REMOTE). OBSERVE POLARITIES: THE +S TERMINAL (TB1-6) MUST BE CON-
NECTED TO OUT (TB1-7) (LOCAL) OR +LOAD (REMOTE), AND THE - S
TERMINAL (TB1-3) MUST BE CONNECTED TO EITHER –OUT (TB1-2) (LOCAL) OR
–LOAD (REMOTE).
Figures 2-4 and 2-5 are typical load connection diagrams illustrating the configurations
explained in the following paragraphs.
