HEP-2300 is a 2300W industrial AC/DC power supply featuring the outstanding capability to operate under
highly humid, dusty, oily, and high-vibration harsh environment. The entire series is housed with the
aluminum case and fully potted with heat-conducted glue. Adopting the full range 90~305VAC input, the
entire series provides an output voltage line of 55/115/230/380VDC. In addition to the high efficiency up to
95.5%, that the whole series operates from -40℃ ~ 70℃ under air convection without fan. HEP-2300 has the
complete protection functions and 10G anti-vibration capability; It is complied with the international
safety regulations such as TUV EN62368-1 UL62368-1 and design refers to EN61558-1 and EN60335-1.
HEP-2300 series serves as a high performance power supply solution for various industrial and telecom
applications. In addition, the 55V model also supports charge function for lead-acid and lithium ion-
batteries.

11.Safety Guidelines
nRisk of electrical shock and energy hazard, all failure should be examined by
a qualified technician. Please do not remove the case fr m the power supplyo
by yourself.
nPlease do not change any component on the unit by yourself or make any
kind of modification on it.
nThe AC voltage range is 100 – 277Vac (47 – 63Hz), please do not connect the
supply to AC gird out of the range.
nPlease do not stack any object on the unit.
nThe safety protection level of this supply is class I. The Frame Ground ( )“”
of the unit must be well connected to PE (Protective Earth).
nThe device should be installed in a Restricted Access Location, such as
telecommunication facilities, and accessible only to skilled persons.
WARNING: For 115V/230V/380V models
Burn hazard, the surface becomes hot while operating.
If maintenance is required, please turn off the device for
at least 30 minutes to cool down before touching.
Attention : Modèles 115V/230V/380V uniquement
Risque de brûlure, la surface devient chaude pendant
l'opération. Si un entretien est requis,
veuillez éteindre l'appareil pendant au moins 30 minutes
pour refroidir avant de le toucher.
l'appareil doit être installé dans un endroit à accès
restraint, tels que les installations de telecommunication,
et accessible uniquement aux personnes compétentes.

1. Choose the right and suitable cable size for connection between the
HEP-2300 and the loads/batteries. Please refer to 3.3 DC cable size
selection.
2. Connect the DC positive polarity of the supply to the positive of the
loads/batteries and connect the DC negative polarity of the supply to
the negative of loads/batteries. Make sure there is no reverse polarity
or short-circuit on the connection.
3. Connect the supply to the AC grid, FG to the earth, AC/N to the neutral
and AC/L to the live.

Wire connections should be as short as possible and less than 1 meter is
highly recommended. Make sure that suitable wires are chosen based on
safety requirement and rating of current. Small cross section will result in
lower efficiency, less output power and the wires may also become
overheated and cause danger. For selection, please refer to table 3-1.

5.Operation
Terminal and wiring types are suitable for power supply and charger
applications in harsh environment. Factory setting is at power supply
mode. For charger mode, please refer to 5.10.
NOTE: Only 55V model has charger mode
Harness connector type is suitable for cell site applications. There are
three outputs with different current capacity at DC end, which can be
connected to antennae with different power rating, such as 3G -5G. In
addition, the DC end also supports battery back-up input so that the
HEP-2300 can continue operating without interruption even if the
grid power is lost, improving the reliability of the system.
NOTE: a. The three DC outputs are connected together internally, so,
one of them in over current condition will cause the whole
unit . It is suggested to add current limitingshutting down
equipment at each output to prevent system fail.
b. Please set the unit at charger mode when battery back-up is
connected. Please refer to 5.10.
c. Please make sure the battery back-up is within the voltage
range of the system before connecting.

5.3 Inrush Current Limiting
5.4(PFC)Power Factor Correction
5.5Output Voltage Adjustment
●Built-in AC inrush current limiting circuit.
●Since the inrush current limiting circuit mainly consists of a NTC
thermistor and a relay, inrush current will be much higher than the
specified value if the thermistor in AC side is not allowed sufficient
time to cool down. After turning off the supply, a 10 second cool
down period is recommended before turning on again.
●Built-in active power factor correction (PFC) function, power factor
(PF) will be 0.95 or better at full load condition. PF will be less than
0.95 if it is not at full load condition.
●Output voltage can be adjusted via SVR, PV or communication
interface.
Output voltage can be adjusted via the SVR of the panel. Please refer to
the diagram below for the location. After voltage setting, please reinstall
the waterproof plug back to ensure waterproof performance.

charging current to 10% of rated current.drops
Suitable for lead-acid batteries, such as flooded water type, Gel
colloid type, AGM adsorption glass fiber and lithium batteries, such,
as lithium iron, lithium manganese, ternary lithium.--
