The 1-kW charger series offers a universal input range of 90-264 VAC and can handle standard wall outlet voltages with a frequency range of 47 to 63 Hz across the globe. It includes a typical power factor correction (PFC) of 0.98. The series also features output voltages ranging from 28-58.8 V@18 A and 43-86 V@12 A with ultra-high efficiencies of up to 92%.
The AC chargers offer several self-protection features including OVP, OCP, SCP, OTP, RPP and UVLO. Other features include a turn-on delay of 5 s max at full load and status indication and control via CAN communication and a color LED indicator.
The case temperature range is -40°C to 80°C (60°C with handle) and the storage range is -40°C to 85°C. The EVC1000 series meets UL/CSA62368 and EN60335 safety standards and is IP67 rated.
The Diamond Series is available in on-board and off-board versions, with or without a handle, and in connector or flying lead versions. It also includes a fan that turns on at elevated temperatures. The chargers measure 251 × 137 × 80 mm (9.9 × 5.4 × 3.15 inches), excluding the handle. Weight is 3.8 kg (8.4 lbs.)
