These racks are available in configurations for 12KW (up to four modules) and 24KW (up to eight modules). Multiple racks can be paralleled for higher power systems, up to 24KW or more.### Control and Communication* **Programmable Control:** The iHP series offers programmable voltage or current sourcing capabilities.
* **Control Interfaces:**
* Analog 0-5V or 0-10V for voltage or current
* Digital: Ethernet UDP, RS485, CAN, or Ethernet TC/IP with PowerPro Connect Module option.
* Command protocol is patterned after the PMBus specification using a proprietary transaction protocol.
* **Firmware:** Field upgradeable firmware.
* **Slew Rate:** Programmable slew rate up to 200 Hz for fast current changes.### Compatibility and Standards* **SEMI-F47 Compliance:** iHP24L3A & iHP24H3A modules can support SEMI-F47 compliance for full load without derating. Line interruption is designed to meet SEMI-F47-0706, 53, 58, S14 at nominal input voltages (Non "S" models do not apply).
* **Safety Approvals:**
* UL 60950-1 2nd Edition
* EN60950-1
* CAN/CSA-C22.2 No.
* **Input Phase Detection:** Loss of phase will inhibit unit off; housekeeping/comms must continue with phase loss. Undervoltage shutdown occurs at 15% below nominal, with turn-on at 12% below nominal.Why Choose Aumictech for Emerson / Artesyn / Astec 73-936-0048?
