Sefram

Description :

The 1657 is an AC power source that provides high conversion efficiency and low distortion output. A built-in PFC provides an input power factor of 0.99 at full load. The AC source supplies up to 1500 VA through its universal line output terminal and can operate in one of two voltage ranges, 135 V or 270 V, with 0.1 V resolution. The bright display constantly monitors the output voltage, current, power and frequency and also indicates the selected range and mode of operation. The front panel interface is easy-to-use and includes a control knob for quick setting of voltage and frequency parameters. The 1657 can also be controlled remotely via RS232 interface. This 1500 VA rated AC power source is ideally suited for industrial product testing applications where power conversion or performance verifications is needed. The 19 inch rack-mountable design with front to rear airflow ventilation, allows for a compact form factor in automated test environments.
