HSPSERIES OPR 050614
1.4.7 AUXILIARY SUPPLY: Logic-level secondary output provides up to 0.5 watts of power at 5V
d-c. This output is isolated from the output and is unaffected by the status of the main output.
Provides power for external Remote Inhibit controls (see PAR. 3.11).
1.4.8 OVERCURRENT/UNDERVOLTAGE PROTECTION: Switch-selectable option provides the
user load protection against long-term output overloads or undervoltage conditions (see PAR.
3.9).
1.4.9 CURRENT WALK-IN: Switch-selectable option provides control of output current rise rate
based on Bellcore TR-TSY-000947 requirements for battery chargers (see PAR. 3.10).
1.4.10 REMOTE RESET: Switch-selectable option provides capability to reset the latch used by the
overvoltage protection circuitry to disable the output regulator, using the Remote Inhibit control
lines (see PAR. 3.12).
1.5 OPTIONS
HSP options are described below; more than one option may be incorporated into any HSP
Power Supply.
1.5.1 METERS (M SUFFIX): HSP power supplies are available with an optional front panel meter
which displays output voltage and output current (switch selectable). Refer to PAR. 3.15 for
operation.
1.5.2 BATTERY CHARGERS (B SUFFIX): The battery charger option adds switch selectable “float”
and “equalize” functions which provide two separate voltage regulation settings, as well as an
expanded window for the output voltage fault detector compatible with normal battery operating
voltages (Refer to PAR. 3.16 for operation).
1.5.3 INTERNAL BLOCKING DIODE (R SUFFIX): This option adds a blocking diode in series with
the output, required for “hot swap” applications.
1.6 ACCESSORIES
Accessories for HSP Power Supplies are listed in Table 1-3.
