Product Description:
The E11A102B011TWUJ is an uninterruptible power supply produced by Sanyo Denki for the SANUPS Power Supplies series. Intended for machine tools, inspection stations, and other automated assets, the unit maintains regulated AC power when the mains voltage is lost or disturbed, allowing an orderly shutdown or uninterrupted processing. It employs a hybrid topology that combines line-interactive efficiency with double-conversion precision, while forced-air cooling limits internal temperature rise. System status and event logs can be accessed through the onboard RS-232C interface, and input power is accepted through a NEMA 5-15P plug that matches standard North American branch circuits.
The output stage is rated at 1 kVA, indicating the maximum apparent power that can be delivered to connected loads, and its real power ceiling is 0.7 kW. The unit supports a 0.7 lagging load power factor, accommodating the reactive component of equipment connected to the four NEMA 5-15R receptacles. Voltage quality is maintained with total harmonic distortion limited to a maximum of 3% under linear loading, preventing excessive heating in sensitive drives and motors. Touch-current safety is supported by input leakage current limited to a maximum of 3 mA, keeping chassis current below the threshold set by industrial safety standards. Acoustic output does not exceed 40 dB, so the supply can be mounted in control cabinets located near occupied work areas without adding significant ambient noise.
Energy storage is handled by a small VRLA battery pack with a capacity of 204 Wh, furnishing enough reserve for the specified 5-minute backup interval at full rated load. During discharge or charger operation, the thermal load transferred to the enclosure is 125 W, a value that must be considered when sizing panel ventilation. The enclosure, cabling, and batteries have a total mass of 17 kg, supporting stable floor or rack mounting without imposing excessive structural load. The battery reserve allows critical equipment to continue operating briefly during an outage, while the regulated output helps protect connected loads from abrupt power interruptions.
