SENS EnerGenius® DC Compact Technical Manual
8
Output Ripple
< 30 mV with battery, <100mV off-battery for 120VDC,
<200mV off-battery for 240VDC. Delivers fast-responding,
stable, well-filtered DC without battery.
Step response
8ms typical without battery, to recover within 1% of rated
output voltage from load step change of 50% rated output
current
Output protection
Electronic current limit. 2-pole UL 489 listed circuit breaker.
10 kAIC, lockable
DC surge protection
Layered electrical transient defenses. Optional UL1449 Open
Type 2 Listed supplemental surge protection, alarmed and
with field replaceable elements, surge capacity rated 75kA
8/20 µs; visual and remote indications.
Battery types
Flooded lead-acid, AGM, Ni-Cd, VRLA, and lithium
DC power supply operation Delivers fast-responding, stable, well-filtered DC without
battery
Battery temp.
compensation
Standard. On-board sensor modifies output voltage when
temperature is between 0°C and+40°C. Slope adjustable,
factory set to
–
0.18% per degree C. Optional remote battery
monitor provides battery temperature probe.
Dead battery charge
Starts into and recharges zero-volt battery
Parallel/load share
operation
Two or more independent chargers actively current share
and synchronize all modes for increased current or fault
tolerance when a common RJ-45 network cable is connected
to each charger’s paralleling bus
Output blocking protection
Prevents sparking during battery connection; serves as an
"OR" diode to isolate a non-functioning charger from others
in a redundant charger configuration
Adjustment &
Controls
Charge mode control
Fully automatic patented Dynamic Boost system. Manual
boost, timed boost & battery commissioning charging
options are available from front panel control.
Front panel control
Change all parameters including voltages, current limits,
alarm parameters, relay assignments, network
configurations, time-outs, and more
Local computer
Change all parameters, troubleshoot, create/save
configuration files for quick download to chargers using
network connection and SENS Setup Utility software

Status Reporting
LEDs
Two multi-color front panel status LEDs
Metering
AC/DC Voltmeter accurate to ±1%; AC/DC ammeter to ±1%;
AC frequency meter to ±1.5%; DC Output Watts; DC Output
as a percent of maximum rated output
Status display
20-character display of status & alarm messages.
Data logging
Data logging to internal nonvolatile memory, based on events
and at fixed times. Logs retrieved using computer network
connection.
Alarms
Alarm Outputs
Factory set, field reconfigurable, latching or non-latching.
Alarms available via communication port, alarm relays, and
on front panel display.
