The All 48-series lasers operate from standard 30VDC power supplies, and can be either fan-cooled (48-1 and 48-2 models), or water cooled. Synrad’s 48-series lasers are ideal for incorporation into marking, engraving, and small cutting systems, where performance, low price and high reliability are essential. Synrad lasers can be operated from 0-100% duty cycle, with laser power adjusted using a pulse width modulation (PWM) control. The laser is controlled directly with a TTL signal (rear-mounted BNC connector). Alternatively, a DB-9 connector provides remote access to all laser functions, including laser control, fault conditions monitoring, remote interlock, and failure shutdown options. After 20 years, This product remains the industry standard for establishment, dependability, long lifetime and cheaper cost. This will assure the customer that the laser will resist the harsh requirements of modern industrial environments.
