HEP Series: Unyielding Power (100W ~ 1000W)
The standard HEP series is the backbone of outdoor and heavy-industry power. With standard IP65 protection (and IP68 options capable of underwater operation), they are impervious to dust, humidity (up to 95% RH), and severe vibrations.
| Model Series | Power Range | Available DC Outputs | Max Efficiency | Operating Temp. |
|---|---|---|---|---|
| HEP-100 / 150 / 185 | 100W - 187W | 12V, 15V, 24V, 36V, 48V, 54V | Up to 94% | -55°C ~ +70°C |
| HEP-240 / 320 | 240W - 320W | 12V, 15V, 24V, 36V, 48V, 54V | Up to 95% | -55°C ~ +70°C |
| HEP-480 / 600 | 480W - 600W | 12V, 24V, 36V, 48V, 54V (up to 9 options) | Up to 96% | -55°C ~ +70°C |
| HEP-1000 | 1000W | 24V, 48V, 100V | Up to 96% | -40°C ~ +70°C |
Heavy-Duty & High-Voltage Series (1500W ~ 3500W)
When raw power and specialized high-voltage outputs are required, the UHP, PHP, CSP, and high-wattage HEP models step in. These units rely on sophisticated conduction or water cooling to maintain a slim, fanless profile.
| Model Series | Max Power | Key DC Outputs | Cooling Method | Application Focus |
|---|---|---|---|---|
| UHP-1500-HV | 1500W | 115V, 230V, 380V | Conduction Baseplate | Slim Profile / High Voltage |
| HEP-2300 / HV | 2300W | 55V / 115V, 230V, 380V | Fanless / Potted | Harsh Environment / Telecom |
| CSP-3000 | 3000W | 120V, 250V, 400V | Built-in Fan | Single Output High Voltage |
| PHP-3500 / HV | 3500W | 24V, 48V / 115V, 230V, 380V | Conduction / Water Cooled | Enclosed Industrial Systems |
Intelligent Charging & Smart System Integration
Beyond standard power supply operations, these series offer dedicated battery charging capabilities and deep system integration for automated environments.
Battery Charger Solutions
- HEP-600C (Dedicated Charger): Designed for open & sealed lead-acid batteries. Employs a robust 3-stage charging curve (Constant Current, Constant Voltage, Floating Charge) for 12V, 24V, and 48V systems.
- HEP-1000 & HEP-2300 (Dual Mode): Highly versatile units that seamlessly switch between standard power supply mode and programmable battery charger mode.
Smart Signals & Communications
- PV / PC Control: Programmable Voltage (PV) allows output voltage scaling from 50~125%. Programmable Current (PC) allows constant current limiting from 20~100%.
- Digital Protocols: HEP-1000 and above support PMBus and CANBus communication for real-time monitoring and parameter adjustment (compatible with the SBP-001 smart programmer).
- Auxiliary Functions: Equipped with DC-OK TTL signal monitoring, Remote ON/OFF, and a built-in 12V standby power output for driving sensors or external boards.
Physical Dimensions & Thermal Guidelines
Dimensions (L * W * H)
- HEP 100/150/185: ~228 * 68 * 38.8 mm
- HEP-240 / 320: 252 * 90 * 43.8 mm (Max)
- HEP-480 / 600 / 1000: Range from 262mm to 310mm length.
- UHP-1500-HV: 290 * 140 * 41 mm
- HEP-2300: 375 * 280 * 88 mm
- CSP-3000: 278 * 177.8 * 63.5 mm
- PHP-3500: 380 * 141.4 * 60 mm (Conduction) / 72 mm (Water Cooled)
For conduction-cooled high-power models (like UHP and PHP series), it is mandatory to mount the power supply securely to a thermally conductive surface—such as an aluminum plate (e.g., 1000mm x 1000mm x 5mm)—to ensure optimal heat dissipation. Failure to provide adequate thermal relief may trigger Over Temperature Protection (OTP) and cause output power derating.
