Power Factor Correction (PFC) standard on all except older models (350W
Series includes PFC).
User configurable
o multi-output 3U power rack for up to (3) 350W modules, (6) 150W
modules, (8) 50W or 100W modules, or (4) 300W, 600W, or
1200W/1500W modules in a rack, as well as many combinations within
a rack and the ability to parallel racks for added power.
o multi-output 1U power rack for up to (4) 50, 100 or 150 watt modules,
as well as many combinations within a rack and the ability to connect
racks in parallel or series for added power or redundancy.
o For example, the 1500W models with the RA 19-4C Rack Adapter can
be configured as two N+1 redundant systems of 1500W each, a single
N+1 system of up to 4500W, or a single parallel combination producing
up to 6000 watts of d-c. Built-in current balancing and OR-ing diodes
allow all these configurations. Two similarly populated racks could be
connected in parallel for a 6000W redundant system, or the racks could
be connected in series to increase voltage (500V d-c max.).
Front panel meter optional feature (300W, 600W, 1200W/1500W Models
only).
Parallel for N+1 redundancy.
Or-ing diodes built in.
Local voltage control trimming from front panel.

Remote voltage control of 300W, 600W, 1200W/1500W modules via trimpot
or voltage source.
Remote ON/OFF of 300W, 600W, 1200W/1500W modules using either an
external power source (voltage applied to RC terminals) or by mechanical or
logical closure of a contact (without external power source). (Available as an
option for 50W, 100W and 150W HSF-PFC and HSF-1UR models; contact
factory for details.)
Individual current monitor (Available as an option for 50W, 100W and 150W
HSF-PFC and HSF-1UR models and for 300W, 600W and 1200/1500 HSF
models; contact factory for details.)
Plug-in construction. Easy mount and dismount.
Keyed construction to prevent incorrect module placement. The HSF are
keyed according to their voltage rating. When the corresponding rack adapter
key (pin) is installed by a user, only an HSF of the correct voltage can be
inserted into the keyed slot.
Built-in EMI filter attenuates the conducted noise below the requirements of
both FCC and VDE 0871 for Class B computing devices.
Separate remote error sense terminals: (all except 1200W/1500W models)
to compensate for voltage drop of connecting wires
Forced current share is used to configure an N+1 system. When the current
share bus of paralleled HSF are connected together, the load current divides
equally. If one unit fails, the remaining units will divide the load equally among
themselves and continue to supply uninterrupted current to a critical load. The
failed unit is isolated by built-in or-ing diodes.
Built-in alarm relay provides either normally open (close on failure) or
normally closed (open on failure) contacts that may be used to provide an
external failure indication. 300W, 600W and 1200W/1500W modules also
have a logic alarm signal (±PF) that performs the same function.
24 pin connector used to obtain mains power and provide output via
corresponding mating connector in the rack adapter.
Reset Button (300W, 350W, 600W and 1200W/1500W units only) to restore
the output if the unit shuts down after sensing an over- or undervoltage
condition, thermal overload, or fan malfunction.
Safety: Designed to meet UL: 60950; CSA:C22.2 60950; TUV: EN60950 (a-c
input only).
CE Mark: Units are CE marked per the Low Voltage Directive
(LVD),73/23/EEC and 93/68/EEC.
Bellcore Requirements: Designed to meet NEBS GR-63-CORE. Certification
passed: RA 19-6B with six HSF 150W units tested per GR-63-CORE, Level 4
(Earthquake and office vibration).

Kepco Series RA 19-(X)B Rack Adapter
Kepco Series RA 19 Rack Adapters are
specifically designed for the installation of
Kepco's Series HSF hot swap power
supplies into 19-inch EIA standard
equipment racks. These racks allow
redundancy between power supplies
contained within the rack as well between identically populated racks.

RA 19-(X)B rack adapters accommodate Kepco 3U 50W, 100W, 150W (Series
HSF-PFC and Older HSF 50W, 100W, 150W and 350W (Series HSF) power
supplies. RA 19-(X)B models are recognized by UL and CSA.
The RA 19-1U rack adapter accommodates 1U height 50W, 100W and 150W
low profile (1U size) power supplies (Series HSF-1UR) and older Series 50W
and 100W HSF-1U)
The RA 19-4C rack adapter accommodates Kepco 3U 300W, 600W, and
1200W/1500W (series HSF) power supplies. This rack adapter features two
setbacks to accommodate both swing racks and limited depth applications.

Individual racks may also be connected in parallel for greater output current or series
for greater output voltage. Optional brackets are now available to allow RA 19(X)B
rack adapters to be installed in 23-inch or 24-inch racks. Other Series RA 19 rack
adapters are compatible with standard
extenders for 23-inch or 24-inch racks.

Kepco RA 19-4C Rack Adapter

RA 19-3B for 3U 350W HSF power supplies (1/3 rack)
RA 19-6B for 3U 150 Watt HSF-PFC (or HSF) power supplies (1/6 rack)
RA 19-8B for 3U 50 Watt or 100 Watt HSF-PFC (or HSF) power supplies (1/8
rack)
RA 19-4B for a mix of the 3U 1/3 (two), 1/6 and 1/8 rack sizes
RA 19-5B for a mix of the 3U 1/3 (one), 1/6 and 1/8 rack sizes
RA 19-7B for a mix of the 3U 1/6 and 1/8 rack sizes
RA 19-1U for 1U size HSF-1UR (or HSF-1U) 50W, 100W or 150W power
supplies (1/4 rack),
RA 19-4C for 3U HSF
300W, 600W, 1200/1500W
power supplies (1/4 rack),

Kepco RA 19-1U Rack Adapter
Filler panels are available to fill
unused slots.

The rear panel contains the fixed
power and signal connections. The other side of the rear panel is an internal PCB
back plate which has connectors which interface directly with the power and signal
connectors of HSF Series power supplies, permitting hot swappable insertion and
extraction. User-configurable keying ensures that only the correct power supply can
be installed in a keyed slot.

The HSF Power Supplies each provide a normally closed (N.C.) and normally open
(N.O.) line referenced to common (COM) for use as an alarm at the users discretion.
The alarm circuit is independent from the power configuration (series, parallel or
independent). The N.C. line opens upon failure, the N.O. line closes upon failure.
The 300W, 600W, and 1200W/1500W modules also have a logic alarm signal (±PF)
that performs the same function.

All mechanical and electrical specifications are contained in the mechanical outline
drawings. The rack adapter is user-configurable for parallel, series, or independent
power supply operation. Forced current sharing and OR'ing diodes for N+1
redundancy are built in to the HSF power supplies.

HSF 150W Series Power Modules and the RA 19-6B Rack Adapter have been
tested and deemed compliant with the requirements for physical protection of
Network Equipment-Building System (NEBS) for earthquake zone 4 per GR-63-
CORE, including both damage resistance and functional performance requirements.
This means that the power assembly suffered no physical damage as a result of the
testing and provided full specified performance both during and after exposure to the
test environment.
